Botanical Acclimatization and Earth-Shaping: From Hanbury’s Exotic Terraces to Bussana Vecchia’s Post-Seismic Revival

Along the Ligurian Riviera di Ponente, two sites embody radically different yet complementary forms of human ingenuity applied to challenging coastal terrain. At La Mortola near Ventimiglia, the Hanbury Botanical Gardens cascade down tiered cliff faces in one of Europe’s most ambitious botanical acclimatization experiments. Twenty kilometers east, the ruined medieval village of Bussana Vecchia — devastated by the 1887 Ligurian earthquake — has been partially consolidated and reoccupied by an international community of artists. Together, these landscapes reveal the human capacity to reshape and sustainably inhabit an unforgiving Mediterranean coastline.

Key Takeaways

The Hanbury Botanical Gardens at La Mortola were established in 1867 by British merchant Thomas Hanbury, who exploited the site’s steeply south-facing microclimate and existing terraced infrastructure to acclimatize plant species from five continents — a collection that numbered nearly 5,800 documented taxa by 1912 and is today administered by the University of Genoa.
Dry-stone retaining walls form the structural backbone of the gardens’ terracing system; their battered profiles, interlocked courses, and rubble-filled drainage layers distribute hydrostatic pressure and control slope erosion along one of the most geologically dynamic coastlines in northern Italy.
Water management at the Hanbury Botanical Gardens relies on a layered system of cisterns, surface channels, and gravity-fed distribution lines — a technology inherited from centuries of Ligurian agricultural terracing and adapted here to serve a botanical collection whose irrigation demands far exceed those of any prior agricultural use of the site.
Bussana Vecchia was largely destroyed by the Ligurian earthquake of February 23, 1887 — estimated at magnitude 6.7 — and officially declared unfit for habitation in 1889; its reoccupation by artists from the late 1950s onward represents one of the earliest documented instances of post-seismic informal adaptive reuse in southern Europe.
The structural consolidation carried out by artists in Bussana Vecchia proceeded through improvised, community-driven interventions rather than formal conservation programs, raising enduring questions about heritage governance and the legitimacy of informal occupants as custodians of damaged historic fabric.
The coastal acclimatization logic that defines the Hanbury Botanical Gardens finds independent parallels at the Royal Botanic Gardens, Peradeniya in Sri Lanka and in the terraced agricultural landscapes of Madeira — a convergence of solutions to similar microclimatic challenges that emerged independently across widely separated geographies.

The Ligurian Riviera di Ponente: A Coastline of Extremes

The western arc of the Ligurian coast — the Riviera di Ponente, stretching from Genoa toward the French border at Ventimiglia — is a landscape of concentrated contrasts. The Ligurian Alps descend precipitously toward the sea, leaving virtually no coastal plain; settlements cling to narrow benches and hilltops between cliff and shore. This topography has historically demanded ingenious landscape engineering from its inhabitants, who over many centuries constructed the terrace systems, retaining walls, and water-distribution networks that define the agricultural and ornamental landscape of the western Riviera.

The climate reinforces the coastal character. Warm, dry summers, mild winters, and reliable humidity from the sea make the Riviera di Ponente one of the warmest zones in mainland Italy. Frost is rare near the shore, and the region has historically supported citrus cultivation — unusual so far north in Europe — alongside olive groves, vineyards, and flower cultivation for the international cut-flower trade centered on Sanremo and its surroundings. This climatological endowment attracted sustained horticultural ambition, culminating in the Victorian and Edwardian gardens established by British and other northern European residents who recognized in the Ligurian microclimate an opportunity to cultivate plants from subtropical and tropical climates in an otherwise temperate country.

The geological substratum of the Riviera di Ponente is predominantly crystalline and sedimentary limestone, interspersed with schists and some igneous rocks. These substrates drain freely and warm quickly — characteristics that both complicate irrigation management (water penetrates rapidly, leaving little surface reserve) and benefit root health in species sensitive to waterlogging. The combination of free-draining substrate, southward orientation, and maritime thermal moderation creates microclimatic conditions that distinguish the Riviera di Ponente as one of the exceptional botanical opportunities in the western Mediterranean. The Mortola promontory, which juts southward from an altitude of approximately 103 meters directly into the Ligurian Sea, concentrates these advantages to a degree found at few other sites on the Italian mainland.

The same topographic severity that created horticultural opportunity also created vulnerability. Hilltop settlements built on thin soils and rocky outcrops, connected by steep mule paths, were poorly equipped to resist the seismic events that periodically ripple through the underlying fault systems of the northern Apennine-Alpine junction. The 1887 earthquake that destroyed Bussana Vecchia was not an isolated event in the region’s geological history but the largest and most destructive expression of a tectonic reality that has shaped coastal Liguria throughout the historic period. Reading the landscapes of the Riviera di Ponente means reading both the ingenuity with which human communities exploited its climatological gifts and the geological fragility against which that ingenuity was always deployed.

The two sites examined in this article — the Hanbury Botanical Gardens and Bussana Vecchia — sit at opposite ends of a twenty-kilometer stretch of this coastline, and they represent opposite poles of the human relationship with challenging terrain. One is a triumph of patient landscape engineering and botanical ambition, built on controlled cultivation and scientific curiosity; the other is a monument to catastrophic geological disruption and the tenacious human desire to inhabit even a devastated place. Taken together, they illuminate the full range of what the Ligurian coastal landscape has required, and inspired, in those who chose to engage with it.

Thomas Hanbury and the Victorian Vision of Botanical Acclimatization

Thomas Hanbury (1832–1907) was a British merchant who built his fortune in Shanghai during the mid-nineteenth century, trading in spices, tea, and silk during a period of rapid commercial expansion in the Chinese treaty ports. He belonged to a remarkable generation of Victorian entrepreneurs whose wealth, combined with serious intellectual interests in natural history and horticulture, produced some of the most significant private botanical gardens in Europe. In 1867, Hanbury purchased the Palazzo Orengo estate on the Mortola promontory near Ventimiglia, at the western extremity of Italy’s Ligurian coast, and immediately began transforming its existing terraced olive groves and vineyards into a garden of international botanical ambition.

His brother Daniel Hanbury (1825–1875) was a distinguished pharmacognosist — a specialist in the biological sources of pharmaceutical compounds and author, with Friedrich Flückiger, of the landmark reference work Pharmacographia (1874). Daniel’s scientific rigor shaped the early botanical program of the garden, directing attention toward plants with medicinal, economic, and scientific significance alongside the ornamental species that gave the site its visual character. This dual mandate — beauty and utility, aesthetic arrangement and botanical experimentation — remained central to the garden’s identity through the decades of Thomas Hanbury’s stewardship. Thomas was also guided by Ludwig Winter, a German botanist and landscape designer who served as head gardener during a formative period of the garden’s development, and by a succession of German-trained scientific botanists including Gustav Cronemayer, Kurt Dinter, and Alwin Berger, whose expertise shaped both the collection strategy and the published catalogues that made the garden an international botanical reference.

The concept of botanical acclimatization that the Hanbury enterprise embodied was a defining preoccupation of Victorian natural science. The hypothesis, broadly stated, held that plants from tropical or subtropical climates could be successfully cultivated in temperate settings if conditions of exposure, drainage, humidity, and thermal moderation were sufficiently favorable, and that successive generations grown in these conditions might gradually adapt to the new climate. Whether acclimatization in this stronger genetic sense is possible remains debated in botanical science — the prevailing view has moved toward recognizing phenotypic plasticity rather than rapid heritable adaptation as the operative mechanism — but as a practical horticultural strategy, the exploitation of favored microclimates to extend the range of cultivable exotic plants proved enormously productive at La Mortola.

Under Thomas Hanbury’s direction, the garden accumulated plant collections from southern Africa, Australia, South America, Asia, and the Canary Islands. Species from the Cape Floristic Region, the Australian scrublands, the Himalayan foothills, the desert-edge ecosystems of North Africa, and the humid subtropical forests of the Americas found space on the terraced slopes of La Mortola, where the maritime microclimate offered conditions that few other locations in mainland Italy could replicate. By 1912 — five years after Thomas Hanbury’s death — the Hortus Mortolensis, the garden’s authoritative printed catalogue, recorded nearly 5,800 species growing in the open air, a figure that positioned the garden among the most diverse botanical collections in Europe and the Mediterranean world.

After Thomas Hanbury’s death, stewardship passed to his son Cecil Hanbury and subsequently to Cecil’s wife, Lady Dorothy Hanbury, who added landscape elements including viewpoints, avenues, paths, and fountains that gave the garden some of its distinctive spatial character. The Second World War caused severe damage — the gardens became a no-man’s land during the Italian campaign — and Lady Dorothy sold the property to the Italian State in 1960. Management was formally entrusted to the University of Genoa under an agreement concluded in 1983 and operational from 1987; the Liguria Region established the site as a protected area in 2000. This institutional continuity has allowed the garden to maintain its scientific and educational functions, though the resources required to maintain terraced infrastructure on a steep coastal site remain a persistent challenge that even well-endowed institutional management must continuously negotiate.

Soil Stabilization and Microclimate Design at Hanbury Botanical Gardens

The physical infrastructure of the Hanbury Botanical Gardens is inseparable from its botanical achievement. Without the retaining walls that hold the terraced soils in place, without the channels and cisterns that distribute water across a site that drains rapidly toward the sea cliff below, and without the constant maintenance that these systems require, the exotic collections would be as short-lived as the unstabilized slopes on which they grow. The engineering of the garden — its walls, its water systems, its soil management — is not background infrastructure for the plants; it is itself a form of making, as deliberate and consequential as any planting decision.

The Mortola promontory drops steeply from its highest terraces to the sea cliff below, a vertical compression that creates extreme variation in aspect, exposure, and soil depth across a relatively small horizontal distance. The upper terraces receive the strongest winds and the longest periods of direct sun; the lower terraces, sheltered by those above them, accumulate more moisture and maintain more stable temperatures. This vertical microclimate gradient is not simply a natural endowment that the garden exploits — it is partly a product of the terracing itself, which creates sheltered angles, modifies air drainage, and alters the distribution of precipitation through the soil profile. The garden’s designers were alert to these effects: the positioning of particular plant communities on particular terrace levels reflects an understanding of the microclimate differentiation produced by the terraced structure, not only the slope’s general southward orientation.

Hydraulic Systems for Cliffside Irrigation Using Coastal Aquifers

The irrigation challenge at La Mortola is acute. The limestone and schist substrate drains freely, retaining little surface moisture after rainfall. Many of the exotic species cultivated at the Hanbury Botanical Gardens — including plants from sub-Saharan Africa, the Australian interior, and the semi-arid Canary Islands — are adapted to seasonal drought, but the garden also contains plants from humid subtropical and tropical climates that require consistent moisture throughout the growing season. Managing these divergent needs across a steeply terraced site with rapid subsurface drainage demands a sophisticated hydraulic infrastructure.

The broader Ligurian agricultural tradition developed, over many centuries, a system of water management suited to precisely this drainage challenge. Rainwater was collected in stone-lined cisterns positioned at high points on the terraced slopes, then distributed by gravity through surface channels and piped conduits to lower terraces. This gravity-fed distribution system required no mechanical pumping and, once constructed, demanded relatively little maintenance beyond periodic clearing of channels and inspection of cistern integrity. The Hanbury garden inherited and expanded this cistern-and-channel infrastructure — Thomas Hanbury commissioned the construction of a new water supply system early in the garden’s development — scaling it to accommodate the irrigation requirements of a diverse international plant collection that goes significantly beyond the olives, vegetables, and cut flowers that the original agricultural terraces were designed to serve.

The coastal geological setting of the Mortola promontory introduces the possibility of subsurface water sources as a component of the site’s hydraulic picture. Limestone and schist formations along the Ligurian coast can host shallow perched aquifers — lenses of groundwater held above the regional water table by impermeable layers within the rock sequence — and the proximity of the sea creates a freshwater-saltwater interface in the deeper subsurface that influences the behavior of any coastal groundwater system. The extent to which the Hanbury garden has historically exploited discrete subsurface water sources, through wells or targeted drainage capture, alongside its documented surface collection and storage systems is not established in detail by the sources presently available; the core of the documented hydraulic infrastructure remains the cistern-and-channel network inherited from the Ligurian agricultural tradition. What is clear is that the site’s seasonal hydrology — plentiful winter rainfall, near-zero precipitation through the summer months — required the storage capacity that a substantial cistern network provided, buffering against the dry season when tropical and subtropical species face their most acute moisture stress in a Mediterranean climate.

The University of Genoa’s management of the site since 1987 has supplemented the traditional cistern-and-channel system with modern piped water supply and, in some sections, drip irrigation technology capable of providing precisely calibrated moisture to individual plant beds or zones. This technological layering — historic gravity-fed channels over which twentieth-century piped supply and more recent drip systems have been superimposed — is characteristic of long-established terraced sites across the Mediterranean, where the physical infrastructure of earlier agricultural regimes is rarely dismantled but progressively supplemented as new water management capabilities become available. The result is a hydraulic system of considerable historical depth, whose oldest components reflect the water management logic of Ligurian agricultural communities working in the pre-industrial tradition and whose newest components reflect the precision irrigation capabilities of twenty-first-century botanical horticulture.

Retaining Wall Geometrical Profiles for Preventing Coastal Erosion

The dry-stone retaining walls of the Hanbury Botanical Gardens are the most visually conspicuous and structurally fundamental element of the garden’s engineering. Built in the tradition of Ligurian muretti a secco — a technique shared by the coastal terracing systems of the western Mediterranean from Liguria through Provence and Catalonia — the walls at La Mortola vary considerably in scale, from low field boundaries of a single or double course to substantial structures several meters in height where the terrain drops sharply toward the sea cliff.

The structural geometry of a dry-stone retaining wall is governed by the need to resist two primary forces: the gravitational weight of the retained soil bearing laterally against the wall face, and the additional hydrostatic pressure generated when rainfall saturates the soil and the retained mass becomes significantly heavier and more mobile. The classical dry-stone solution addresses both forces simultaneously through its geometric profile. The outer face of the wall is inclined slightly inward — the batter — rather than built truly vertical. This inclination shifts the resultant force vector of the wall’s own weight and the soil pressure toward the base, reducing the overturning moment that would otherwise act on a vertical structure. The degree of batter required depends on the height of the wall, the density and cohesion of the retained soil, and the frequency of saturation events: taller walls retaining heavier, less cohesive soils on slopes with high seasonal rainfall require a more pronounced batter angle.

Drainage management is the second structural imperative. Dry-stone walls, by definition, contain no mortar, which means they are inherently permeable: water can pass between the stones and through the wall body. This permeability, sometimes perceived as a structural weakness, is in practice the dry-stone wall’s primary advantage over mortared or concrete retaining structures in conditions of high rainfall. Where a mortared wall traps water behind its impermeable face — generating hydrostatic pressure that eventually fails the structure at its foundation or causes it to overturn — a dry-stone wall allows water to percolate through its body and exit at the face, maintaining tolerable pressure levels in the retained soil. The rubble fill packed immediately behind the face, chosen for its open, free-draining texture, enhances this drainage function by ensuring that water does not accumulate in the zone of maximum lateral pressure.

At the Hanbury Botanical Gardens, the coastal setting adds a further dimension to the erosion challenge. The sea cliffs at the base of the promontory are subject to direct wave action, which undercuts the slope and can trigger retrogressive failure — the progressive collapse of upper terrace walls following the loss of support from below. The retaining walls on the lower terraces must therefore resist not only the lateral pressure of the soil they contain but also the potential for undermining from marine erosion of their foundations. The traditional response to this risk in the Ligurian coastal terrace tradition involves deeper foundations, the use of larger base stones, and the selection of the most durable available stone for the lowest courses — all measures consistent with the construction visible in the cliff-edge walls of the La Mortola site.

Dry-stone retaining wall maintenance is a continuous obligation at any terraced site, and particularly so at one exposed to the combination of seismic activity, storm rainfall, and coastal wave energy that characterizes the Mortola promontory. Individual stones work loose over time through frost-thaw cycles, root action, and the minor ground vibrations that recur along this tectonically active coast. A dislodged stone creates a point of weakness that, in conditions of heavy rainfall and saturated soil, can initiate a progressive failure of the wall face. The management of the Hanbury Botanical Gardens accordingly incorporates ongoing wall inspection and repair as a core operational function — a commitment that requires both adequate funding and the specialized craft skills that are increasingly scarce as the tradition of dry-stone construction recedes from active practice across Mediterranean Europe. The preservation of the walls is, in this respect, inseparable from the preservation of the botanical collections they support.

Acclimatization Beyond Liguria: Convergent Experiments in Sri Lanka and Madeira

The acclimatization garden as a concept — a defined, managed landscape in which microclimatic conditions are exploited or enhanced to cultivate non-native species — is not a uniquely European or uniquely Ligurian phenomenon. Similar logic, driven by the combination of botanical ambition and favorable local topography, produced comparable institutions across widely separated geographies during the eighteenth, nineteenth, and early twentieth centuries. Two comparanda that illuminate the Hanbury Botanical Gardens through contrast and parallel are the Royal Botanic Gardens at Peradeniya in Sri Lanka and the terraced agricultural and ornamental landscape of Madeira.

The Royal Botanic Gardens at Peradeniya, established in 1821 near Kandy in the central highlands of Sri Lanka, were founded during the British colonial administration as a center for botanical research, acclimatization, and the development of economically valuable plantations. The gardens occupy a river bend of the Mahaweli River at an elevation of approximately 460 meters above sea level, where the highland climate — cooler, wetter, and more temperate than the tropical lowlands — permitted the cultivation of plant species that could not survive the heat and humidity of the coastal zones. The botanical program emphasized plants of economic significance, including cinchona (the source of quinine), rubber, cacao, and a wide range of spice species — a scientific agenda closely analogous to the pharmacognostical emphasis that Daniel Hanbury brought to La Mortola.

The microclimate strategy at Peradeniya is in some respects the inverse of the strategy at Hanbury. Where Hanbury exploits sea-level coastal warmth and humidity to bring subtropical and tropical species into a temperate European setting, Peradeniya exploits highland coolness and moisture to create a temperate niche within a tropical island — a space where species from subtropical and warm-temperate climates could be cultivated and studied in a country whose lowland climate would be inhospitable to them. The direction of acclimatization is thus reversed, but the underlying principle — exploiting a localized microclimatic anomaly to extend the range of cultivable diversity beyond what the regional baseline would otherwise permit — is identical in both cases. Neither garden influenced the design of the other; the convergence in institutional form reflects the convergent demands of the acclimatization enterprise operating across different geographic contexts, not any genealogical connection between the two initiatives.

Both gardens also operated within the same international botanical exchange network — the global web of correspondence, seed exchange, and specimen distribution organized around the major state botanical institutions of the nineteenth century, of which Kew Gardens in London was the most prominent node. This network circulated plant material, horticultural knowledge, and taxonomic expertise across colonial and metropolitan institutions simultaneously, meaning that geographically distant gardens like Hanbury and Peradeniya were, in the history of their collections, connected through the shared infrastructure of Victorian botanical science even when their design approaches diverged.

The terraced landscapes of Madeira offer a different but equally instructive parallel. Madeira rises steeply from the Atlantic Ocean, its terrain composed predominantly of basaltic rock with soils of variable depth and fertility draped over precipitous ridges and deep valleys. Agricultural and ornamental use of this terrain has required, since the island’s settlement by Portuguese colonists in the fifteenth century, the construction of terraced fields — known as poios — retained by stone walls built on principles closely analogous to those of the Ligurian muretti a secco tradition. The walls at both sites exploit the same structural logic: battered faces, interlocked courses, free-draining rubble fill, and through-stones — a convergence of engineering solutions driven by the shared physics of slope retention, independent of any cultural connection between the two traditions.

Madeira’s famous levadas — a network of irrigation channels that carry water from the wet northern slopes to the drier terraced agriculture of the southern and western coasts — represent a hydraulic infrastructure of comparable scale and ambition to the cistern-and-channel systems of the Ligurian coast. The earliest levadas were constructed from the fifteenth and sixteenth centuries onward, and the network has been progressively extended and maintained across the intervening five centuries, creating one of the most elaborate gravity-fed irrigation systems in the Atlantic world. The underlying hydraulic principle — high-point collection of precipitation, long-distance gravity-fed distribution through open or closed channels, terminal delivery to cultivated areas at lower elevation — is precisely that of the Ligurian cistern-and-channel tradition, adapted to a different rainfall distribution pattern (Madeira receives its rain primarily on the northern slopes; Liguria receives it relatively uniformly with a summer minimum) but governed by the same physical logic of using topographic gradient as a free energy source for water distribution.

The Funchal Botanical Garden, established in the twentieth century on the grounds of an earlier private estate on the southern slopes above Madeira’s capital, exemplifies the ornamental application of these terracing and irrigation traditions to botanical collection. Like the Hanbury Botanical Gardens, it occupies a steeply terraced south-facing site with sea views, exploiting a maritime microclimate to support a collection of exotic species that includes many genera found also at La Mortola. The parallel between the two gardens is not one of influence — the Funchal garden was established independently, in a different cultural and institutional context — but of convergent circumstance: two Atlantic and Mediterranean coastal sites where similar microclimatic advantages, combined with the terracing traditions of their respective agricultural cultures, produced broadly similar outcomes in botanical ambition and landscape form. What Hanbury, Peradeniya, and the Madeiran landscape collectively demonstrate is that the acclimatization logic is a response to a universal challenge — how to exploit topographic and microclimatic anomalies to extend cultivable diversity beyond the regional baseline — and that similar challenges reliably generate similar solutions across distant geographies.

Bussana Vecchia: Seismic Catastrophe, Abandonment, and Reoccupation

Bussana Vecchia stands on a hilltop ridge in the Ligurian hinterland above Sanremo, at an elevation that commands views over the coastal plain and the sea beyond. Like many medieval Ligurian villages, it was sited for defensibility rather than accessibility, its compact masonry fabric occupying the full extent of the hilltop in a pattern characteristic of the region’s historic settlement geography. At the heart of this fabric stood the Church of Saint Giles — the village’s principal monument — whose bell tower marked the settlement from the valley below and whose Baroque interior reflected the aspirations of the community in the centuries of relative stability that preceded the seismic disaster of 1887.

On February 23, 1887, an earthquake of estimated magnitude 6.7 struck the Ligurian coast between Imperia and the French border — one of the most powerful seismic events in the recorded history of northwestern Italy. The disaster struck early in the morning while a number of residents had gathered in the Church of Saint Giles for a religious celebration, and the collapse of that building was particularly deadly. The broader village fabric sustained catastrophic damage: Bussana Vecchia’s densely built medieval masonry, without seismic bracing and compressed into the full area of the hilltop, proved deeply vulnerable to the ground motions generated by the quake. Historical sources report several hundred fatalities in the Bussana area, though the precise figure varies across contemporary accounts of an event that caused widespread destruction along a broad stretch of coastline simultaneously.

In the immediate aftermath, survivors were sheltered in temporary encampments on the surrounding slopes. The process of relocation was gradual: by 1889, the Italian authorities had officially declared the village unfit for habitation, and construction of Bussana Nuova — a purpose-built replacement settlement at lower elevation, near the coast and the railway — had begun in earnest. The original village was progressively abandoned, and the Sanremo municipal administration closed access to the ruins. For several decades Bussana Vecchia served as a source of building material, its stone blocks salvaged for construction elsewhere; it was then used as a warehouse for building supplies through the 1940s.

The transformation of Bussana Vecchia from ruin to living community began in the late 1950s, in conditions of considerable hardship. The ceramist Mario Giani — known by his artistic name Clizia — along with the Sicilian painter Vanni Giuffré and other associates, recognized in the earthquake-damaged fabric a combination of atmospheric spatial quality and available (if extremely dilapidated) working space that suited their vision of an artistic community outside the institutional and commercial structures of urban life. The early occupants had no electricity, no running water, and no sanitation services; they worked by candlelight and traveled to Bussana Nuova weekly for basic necessities.

The community grew progressively through the 1960s as word spread through European artistic networks of the experiment underway in the ghost village above Sanremo. Artists, craftspeople, and intellectuals from across Italy and from France, Germany, the Netherlands, Scandinavia, and beyond arrived to claim studio spaces within the ruins. The community drew up a founding statute to regulate its internal social relations: properties were to be understood as available to the community without individual ownership claims, and commercial sale of artworks was initially prohibited — an idealistic architecture of shared life and uncommercial creativity that has been modified in practice over subsequent decades as the community has matured and its relationship with the external economy has evolved.

The legal situation of the Bussana Vecchia community has remained contested throughout its history. The residents hold no formal title to the properties they inhabit; the village is owned by the Italian state or the commune of Sanremo, depending on the parcel, and the occupation has been characterized by Italian authorities at various points as unlawful. Eviction proceedings have been instituted on multiple occasions, and the community has resisted through a combination of organization, public sympathy, media attention, and the practical difficulties of removing an established residential and cultural community from a site that has become internationally recognized. This legal precariousness has defined the lived experience of successive generations of Bussana Vecchia residents and has shaped the nature of the structural consolidation work they have been able and willing to undertake.

Structural Resilience and Bohemian Urbanism in Bussana Vecchia

The urban fabric of Bussana Vecchia, as it exists today, is the product of three distinct phases of structural history: the original medieval construction, progressively modified and densified across several centuries; the seismic damage event of 1887, which transformed the structural inventory of the village in a single catastrophic episode; and the informal repairs and adaptations of the artist community, ongoing since the late 1950s. Understanding the current condition of the village requires reading all three phases together as a layered material record of decisions made under radically different conditions and with radically different means.

Medieval Ligurian villages of the inland hilltop type were built in a tradition of compact, load-bearing masonry in which individual buildings shared structural walls, creating a mutually interdependent fabric. The collapse of one building in such a system is rarely purely local: it typically removes lateral support from neighbors, compromising their structural integrity in turn. The 1887 earthquake did not create a scatter of independently failed buildings but rather a cascading sequence of failures in which the loss of one element weakened those adjacent, and the resulting damage pattern reflects both the quality of the original construction and the network of structural dependencies within the fabric. The village as it stands today is therefore not simply “a ruined medieval village” but a damaged structural network, whose surviving elements are shaped by the interdependencies that governed the failure sequence.

Spontaneous Structural Consolidation of Broken Vaults by Post-War Artists

The structural interventions undertaken by artists in Bussana Vecchia from the late 1950s onward were driven not by conservation principles or engineering analysis but by immediate practical necessity: spaces had to be made safe and habitable before they could be used as studios and homes. The character of the interventions reflects this pragmatic logic throughout, and the result is a body of work that is inseparable from the particular conditions — material scarcity, legal insecurity, craft rather than engineering expertise — under which it was produced.

The most dangerous structural condition in the earthquake-damaged fabric was — and in many sections remains — the partially collapsed vault. Medieval Ligurian residential and sacred architecture made extensive use of barrel vaults and cross vaults in ground-floor spaces, storerooms, and cellars; these elements, constructed in thin tile or rubble masonry, are capable of carrying substantial loads when their geometry is intact but become highly unstable when their springings are displaced or their crowns are cracked. A partially collapsed vault presents a particular hazard: it may retain enough of its geometry to continue spanning for years or even decades while concealing internal cracking and displacement that makes any additional loading — including the ordinary use of the space below — potentially dangerous.

The approach adopted by artists in such spaces appears, from documented accounts, to have been largely empirical. Loose and obviously unstable material was cleared from collapsed sections to reduce the risk of sudden additional failure. Temporary or permanent supports — timber or metal props, partial masonry columns, infill walls — were inserted beneath portions of the vault showing signs of movement. In some cases, entirely new lightweight roofing was constructed over spaces where vaults had failed completely, using metal or timber framing that does not depend on the compromised masonry for its structural support — effectively abandoning the damaged historic element and creating an independent enclosure above or alongside it. These interventions were carried out with the craft skills and available materials of artists, not the structural calculations of engineers, and without the benefit of condition surveys, material testing, or the documented intervention plans that formal conservation programs require.

It would be reductive to characterize this process as merely improvised or structurally uninformed. Many of the early residents of Bussana Vecchia possessed substantial practical skills in stone working, carpentry, and metalworking — skills directly applicable to structural consolidation — and the community developed over time a collective empirical knowledge of the site’s structural behavior. Individual spaces have been occupied continuously for decades; the sustained human presence itself constitutes a form of ongoing monitoring, with experienced occupants alert to signs of movement or deterioration in the structures around them. What this regime cannot provide is the systematic, documented quality assurance and analytical rigor that formal conservation demands, and the result — a body of interventions of highly variable quality, partially reversible and partially not, with limited documentation of what was done where and when — is a structural reality that poses significant challenges for any future formal conservation program seeking to understand and build on what has already been done.

The vault consolidations and structural repairs visible in Bussana Vecchia today should be read as evidence of the particular kind of custodianship that a committed informal occupant community, practicing structural care without institutional support over several generations, can produce: practically effective in many cases, atmospherically authentic in its acceptance of incompleteness and ambiguity, and irreducibly mixed in its long-term structural implications.

Architectural Typology of Medieval Ligurian Village Clusters

The architectural form of Bussana Vecchia belongs to the category of the hilltop cluster village — the villaggio arroccato — that is among the most characteristic settlement types of the Ligurian interior. In this typology, buildings are arranged in concentric or radial bands around a hilltop, with the defensive perimeter often coinciding with the outer walls of the residential fabric: houses at the village edge present their blind rear walls to the exterior, creating a continuous barrier that combined domestic and defensive functions without requiring a separate fortification wall in the early phases of settlement growth. This integration of habitation and defense is a direct response to the insecurity of the medieval Ligurian coast, where raiding — from the sea by North African corsairs and from land by competing feudal powers — made the defensibility of the settlement site a primary organizing principle.

Within this perimeter, the settlement is organized around a system of narrow lanes — caruggi, in the Ligurian dialect — often roofed or vaulted at intervals to create covered passages, that wind between the building masses without pretense of regularity. The organic geometry of the plan reflects centuries of incremental growth and subdivision rather than any single act of planning: buildings were added against existing walls, lanes were routed around obstacles, and the overall fabric developed through the accumulation of individual decisions made in response to local topography and social circumstance. The result is a spatial density and formal complexity that has no equivalent in planned or regularly laid-out settlements, and that contributes significantly to the atmospheric quality that drew the first artists to Bussana Vecchia and continues to attract visitors today.

The constructional system of the medieval Ligurian hilltop village is predominantly load-bearing rubble stone masonry — typically a core of local limestone, lime-mortared and faced with a more carefully dressed outer surface where the wall is visible from lanes or public spaces. Vaulted ground floors are common throughout the fabric, serving as storerooms, wine cellars, and utility spaces; upper stories may be fully masonry-built or, depending on the period of construction and the resources available to the original builder, partially timber-framed with masonry infill panels. The structural hierarchy places the heaviest and most permanent elements at the base — thick walls, stone vaults, rubble foundations — and lighter materials at higher levels, a rational response to the compressive behavior of masonry construction and to the seismic risk that the experience of previous earthquakes had, at least implicitly, registered in the building tradition.

At Bussana Vecchia, the ruin of the Church of Saint Giles gives the site its most dramatic architectural moment: the collapsed nave and apse, the cracked bell tower, the sunken floor open to the sky, the Baroque architectural ornament still legible on surviving wall fragments amid dense vine growth. The church ruin is not inhabited by the artist community — it stands as a monument to the earthquake event itself, visited by residents and visitors alike as a place of reflection on the catastrophe that defines the site’s modern history — but it anchors the spatial organization of the village around it, just as the intact church once did, and provides a visual and emotional center for the contemporary community living in the surrounding residential fabric. The relationship between the functioning artist community and the untouched ruin at its center is one of the most compelling aspects of Bussana Vecchia’s spatial experience: a working, inhabited present wrapped around a frozen, inviolate past.

The Ligurian hilltop village typology — compact, organically grown, structurally interdependent, topographically determined — makes it both highly atmospheric and structurally complex. Its atmospheric quality, which derives from the density, irregularity, and accumulated patina of the medieval fabric, is precisely what attracted the first artists to Bussana Vecchia. Its structural complexity, which reflects the seismic damage and the decades of differential decay and improvised repair, is precisely what makes any formal conservation intervention in the site a matter of demanding analysis and substantial cost. These two qualities — the atmospheric and the structural — are not in opposition; they are products of the same fabric, read through different disciplinary lenses, and understanding either requires understanding both.

Heritage Governance, Conservation Ethics, and the Rights of Informal Occupants

The governance questions raised by Bussana Vecchia are not unique to Italy, but the particular combination of heritage status, seismic history, informal occupation, and contested ownership that characterizes the site makes it an unusually concentrated case study in the tensions that arise when heritage protection law, property rights, and living community interests converge on a single place. These tensions do not resolve neatly in favor of any single framework, and the site’s history offers cautionary lessons for each of the institutional positions that have been taken toward it.

International conservation frameworks — including the Venice Charter of 1964 and the later Burra Charter of 1979, revised 1999 — assign primary responsibility for heritage conservation to the custodial authority, typically the state or a delegated institutional body, rather than to informal occupants. From this perspective, the artist community of Bussana Vecchia might be characterized as unaccountable custodians whose interventions, however well-intentioned, lack the institutional oversight and documentation that conservation standards require. The absence of systematic condition surveys, the use of non-standard and potentially incompatible materials in some structural repairs, and the limited reversibility of certain interventions are genuine concerns when assessed against the heritage conservation frameworks that have developed since the Venice Charter.

Against this institutional critique, a counter-argument rooted in community-centered conservation approaches holds that informal occupant communities are not simply obstacles to institutional conservation but may function as its most effective substitute in situations where institutional capacity is limited or absent. The artists of Bussana Vecchia have actively maintained structures that would otherwise have continued to decay toward total and irreversible loss, have attracted visitors and international media attention that have created a constituency for the site’s preservation, and have demonstrated across more than six decades a depth of commitment to the place and its fabric that intermittent institutional conservation programs, dependent on periodic funding cycles and political will, may struggle to match. From this perspective, the question is not whether the informal occupants meet formal conservation standards but whether the alternative — continued institutional neglect of a legally problematic site — would have produced better or worse outcomes for the fabric that now survives.

The Hanbury Botanical Gardens present a contrasting governance model. The gardens are administered by the University of Genoa under a formal agreement with the Italian state, providing institutional legitimacy, professional expertise, academic continuity, and access to public and private funding for maintenance and development. The Superintendence of Archaeology, Fine Arts and Landscape retains oversight of the historical buildings and structures. This institutional framework provides the quality assurance and documented stewardship that the informal model of Bussana Vecchia cannot, and it has enabled the Hanbury gardens to function continuously as a scientific and educational resource. The challenge here is not governance deficit but resource adequacy: the terraced infrastructure of La Mortola demands continuous investment in retaining wall inspection and repair, soil management, and irrigation maintenance at a scale that institutional budgets in periods of public financial constraint may not fully support.

The two sites thus illustrate complementary governance challenges in heritage management: the informal occupation model of Bussana Vecchia, where community commitment and place-knowledge substitute for but cannot fully replicate institutional capacity and technical standards; and the institutional management model of Hanbury, where formal governance provides legitimacy and expertise but may be constrained by resources insufficient to meet the maintenance obligations of a complex, physically demanding historic site. Neither model is straightforwardly superior; each has demonstrated strengths and documented weaknesses. The most productive analytical reading of both sites is as evidence that heritage stewardship is a problem admitting of multiple partial solutions, each with distinct strengths and failure modes, and that the most productive question for heritage practitioners is not which single model to choose but how to create governance frameworks capable of recognizing and supporting the strengths of community-driven stewardship — the commitment, the place-knowledge, the atmospheric authenticity — while introducing the systematic oversight and technical quality assurance that informal regimes cannot self-generate.

Visiting Hanbury Botanical Gardens and Bussana Vecchia

The Hanbury Botanical Gardens are located at Corso Montecarlo 43, La Mortola, approximately five kilometers west of Ventimiglia along the coastal road, near the French border. The gardens are open to the public throughout the year on a schedule that adjusts seasonally: spring and summer hours are generally longer, with the gardens open daily from 9:30 AM through late afternoon or early evening, and winter hours are reduced. Visitors should confirm the current schedule and any planned closure days through the official Hanbury Botanical Gardens website or the University of Genoa’s published information, as operating arrangements can change. Admission fees apply and contribute to the ongoing maintenance of the garden’s infrastructure.

Access to the gardens from the road entrance requires descending through the terraced levels from the high entry point to the sea cliff at the lower boundary — a vertical descent of approximately 100 meters over the course of the visit paths. The gradient is significant: visitors should anticipate a moderately demanding physical experience, particularly on the ascent return, and sturdy footwear is strongly recommended for the stone paths and uneven terrace surfaces. The upper terraces are more accessible to visitors with limited mobility; the lower cliff sections involve steep paths and exposed terrain that require reasonable physical confidence. The gardens are best explored slowly, allowing time to identify individual species and to appreciate the layered microclimate differentiation between terrace levels.

The most rewarding seasons for visiting are spring, from March through May, when the succession of flowering species across Mediterranean, subtropical, and South African plant communities is at its richest and temperatures are moderate; and autumn, from September through November, when the summer heat has passed, a second flowering season begins for many species, and the quality of light on the cliff-face terraces and the sea below is at its most evocative. Summer visits are possible but hot, particularly on the exposed lower terraces. Winter visits offer a quieter experience with smaller crowds and an instructive perspective on the garden’s structural infrastructure — the retaining walls, cisterns, and channel systems — stripped of much of the foliar cover that during the growing season disguises the engineering that makes the botanical collection possible.

Bussana Vecchia lies inland above Sanremo, approximately six kilometers from the coast by road. The village is accessible by car — limited parking is available at the village perimeter, as the narrow medieval lanes cannot accommodate vehicles — or, in season, by local bus connections from Sanremo whose schedules vary and should be confirmed in advance. Visitors arriving on foot from the parking area enter through the historic gateway and encounter the inhabited artistic studios and workshops almost immediately. Many residents open their spaces to visitors and offer their work for sale; the village sustains a modest economy of artisan crafts and art alongside its primary residential and creative function.

The ruined Church of Saint Giles and the earthquake-damaged civic spaces at the heart of the village provide the most concentrated encounter with the 1887 seismic event and its structural consequences; the contrast between the ruined religious core and the partially inhabited residential fabric surrounding it gives the visit its distinctive spatial and emotional texture. Visitors should treat the inhabited sections with respect for the residents’ privacy: Bussana Vecchia is a home and working community, not a theme park or a museum, and the experience of visiting it is shaped by this reality. There are no formal guided tours or institutional interpretation; the encounter with the site is exploratory and personal, structured by the visitor’s own curiosity rather than by any prescribed narrative.

The two sites can be combined in a single day from a base in Sanremo or Ventimiglia. A morning visit to the Hanbury Botanical Gardens — which rewards two to three hours of slow exploration — combined with an afternoon in Bussana Vecchia, where the late afternoon light gives the ruins and the inhabited lanes their most atmospheric quality, uses the day effectively and provides the natural juxtaposition of two Ligurian experiments in landscape adaptation: one scientific and horticultural, one seismic and social, both irreducibly shaped by the terrain and climate of the Riviera di Ponente.

Frequently Asked Questions

When were the Hanbury Botanical Gardens established and what was Thomas Hanbury’s botanical philosophy?

Thomas Hanbury purchased the Palazzo Orengo estate at La Mortola near Ventimiglia in 1867 and immediately began converting its terraced olive groves and vineyards into a botanical garden of international scope. His philosophy was shaped decisively by his collaboration with his brother Daniel Hanbury, a pharmacognosist who brought scientific rigor to the collection strategy and directed attention toward plants with medicinal and economic significance alongside purely ornamental species. Thomas Hanbury’s broader vision was that of the Victorian acclimatization enthusiast: a conviction that the favorable microclimate of the Mortola promontory — mild winters, reliable humidity, freely draining substrate, strong southern exposure — could extend the range of cultivable exotic plants in temperate Europe far beyond what inland sites could sustain. Ludwig Winter served as head gardener, and a succession of German scientific botanists including Kurt Dinter and Alwin Berger guided the collection. By 1912 the garden’s printed catalogue, the Hortus Mortolensis, documented nearly 5,800 species growing in the open air — a figure that placed the Hanbury Botanical Gardens among the most species-rich botanical gardens in Europe.

What is botanical acclimatization and how does it differ from ordinary horticulture?

Botanical acclimatization refers to the systematic practice of introducing plant species from their native climatic range to a climatically different setting with the goal of establishing them as viable cultivated plants under the new conditions. The concept goes beyond ordinary horticulture in its ambition and scientific framing: where a gardener cultivates an exotic specimen for ornamental effect, the acclimatization practitioner seeks to demonstrate that the species can be reliably cultivated under the new conditions across multiple growing seasons and, in the stronger Victorian formulation of the theory, that repeated cultivation might produce heritable adaptation to the new climate. Modern botanical science understands the primary mechanism as phenotypic plasticity — flexible expression of existing genetic potential under varied conditions — rather than rapid heritable adaptation, but the practical outcome of exploiting favored microclimates to sustain species that cannot survive regional conditions elsewhere remains as horticulturally significant as the Victorians found it. The Hanbury Botanical Gardens represent one of the most sustained and systematically documented applications of the acclimatization principle in European botanical history.

How do dry-stone retaining walls function as ecological infrastructure in addition to their structural role?

Dry-stone retaining walls provide a suite of ecological services that extend significantly beyond their primary function of slope stabilization. The gaps and crevices between stones create nesting and sheltering habitat for a diverse community of invertebrates — insects, spiders, and mollusks — and for small reptiles including lizards that exploit the thermal properties of the stone surface for thermoregulation. Mosses, ferns, and specialized wall flora colonize the moist, north-facing surfaces of walls in shaded positions, adding botanical diversity to the structure itself. The thermal mass of the stone accumulates solar heat by day and releases it gradually through the night, creating a microclimate immediately adjacent to the wall surface that is measurably warmer and more stable than the ambient conditions a few centimeters away — a characteristic that makes the base of a south-facing dry-stone wall a preferred microhabitat for thermophilous invertebrates and specialist plant species. In a botanical garden context, these ecological services complement the structural function: the walls at the Hanbury Botanical Gardens support not only the terraced plant collections above them but an additional layer of spontaneous biodiversity within their own fabric.

What was the scale of destruction caused by the Ligurian earthquake of 1887 and why was Bussana Vecchia so severely affected?

The Ligurian earthquake of February 23, 1887 — estimated at magnitude 6.7 — was one of the most destructive seismic events to strike northwestern Italy in the modern era. The earthquake generated ground motions that proved catastrophic for the masonry settlements of the western Ligurian interior, with damage extending across a broad zone between the provinces of Imperia, Genoa, and Cuneo. Historical accounts suggest that the earthquake claimed an estimated 644 or more fatalities across the affected area, with Bussana Vecchia among the most heavily damaged single settlements. Several factors made the village particularly vulnerable. Its hilltop position concentrated ground shaking relative to valley-floor locations. Its compact medieval masonry fabric — densely built, with shared structural walls and no seismic bracing — was unable to accommodate the lateral forces generated by the earthquake, and the structural interdependency of the fabric meant that the collapse of one element triggered progressive failure in its neighbors. The presence of residents in the Church of Saint Giles at the time of the earthquake increased the human toll in that building. The village was officially declared unfit for habitation by 1889, and survivors relocated to the purpose-built Bussana Nuova.

How did the artists’ community at Bussana Vecchia begin and who were its founding figures?

The reoccupation of Bussana Vecchia by artists began in the late 1950s, in the same period in which a number of ruined or semi-abandoned historic sites across Europe were attracting bohemian communities seeking space outside the institutional and commercial structures of urban life. The ceramist Mario Giani — known universally by his artistic name Clizia — a native of Turin, is consistently identified in accounts of the community’s origins as one of its central founding figures. Together with the Sicilian painter Vanni Giuffré and others, Clizia recognized in the earthquake-damaged village a combination of available space, atmospheric spatial quality, and separation from the mainstream art market that suited a vision of communal artistic life. The community’s founding statute was idealistic in conception: properties were understood as available without individual ownership claims, and commercial sale of artworks was initially prohibited. The colony grew rapidly through the 1960s as artists from across Europe arrived, attracted by the community’s growing reputation, and the village acquired the international bohemian character it has maintained through subsequent decades, though the original idealistic strictures have been significantly modified by the practical demands of decades of inhabitation.

What structural challenges do partially collapsed vaults pose to informal occupants?

Partially collapsed vaults present some of the most hazardous structural conditions in earthquake-damaged masonry buildings, and their assessment is genuinely demanding even for trained structural engineers. When a vault cracks but retains partial geometry, it may continue to span for an extended period while concealing internal displacement and loss of compressive arch action that makes any additional loading unpredictably dangerous. The assessment of a compromised vault’s residual structural capacity requires understanding of its original geometry, the extent and location of cracking, the condition of the abutments and springings, and the nature of any fill above — factors that a non-specialist occupant can observe qualitatively but cannot analyze quantitatively. The informal approach to vault consolidation in Bussana Vecchia — clearing loose material, inserting props, constructing independent roof structures over failed sections — addresses the most acute observable risks through empirical judgment and is often practically effective in the short term. The long-term behavior of partially consolidated historical vaults under repeated seismic loading — a realistic scenario in the Ligurian geological context — is a concern that an informal maintenance regime is not equipped to monitor or address systematically, and it remains the most significant technical vulnerability in the Bussana Vecchia structural picture.

How does the acclimatization approach at Hanbury Botanical Gardens compare to that of the Royal Botanic Gardens at Peradeniya in Sri Lanka?

The Royal Botanic Gardens at Peradeniya, established in 1821 near Kandy in the Sri Lankan highlands, and the Hanbury Botanical Gardens at La Mortola share a fundamental institutional logic: both exploit a localized microclimate that differs significantly from the regional baseline to cultivate species that would not otherwise survive in the setting. At Peradeniya, the mechanism is elevation — the highland climate at approximately 460 meters above sea level is cooler and more temperate than Sri Lanka’s tropical lowlands, permitting the cultivation of subtropical and warm-temperate species in a broadly tropical country. At Hanbury, the mechanism is coastal warmth and humidity — the sea-moderated microclimate of La Mortola supports subtropical and tropical species in a broadly temperate Mediterranean country. The direction of acclimatization is thus opposite — one introduces temperate elements into a tropical setting, the other introduces tropical elements into a temperate setting — but the underlying principle of exploiting a microclimatic anomaly to extend cultivable diversity is identical. Both gardens also operated within the nineteenth-century international botanical exchange network centered on Kew Gardens. Neither influenced the design of the other; the convergence in institutional form reflects the shared demands of the acclimatization enterprise across different geographies, not any genealogical connection.

What is the current legal and heritage status of Bussana Vecchia?

The legal status of Bussana Vecchia’s artist community has remained contested and unresolved throughout its history. The village’s land and built fabric are owned by the Italian state and the commune of Sanremo, depending on the parcel; the resident artists hold no formal property title to the structures they inhabit and have maintained their presence on the basis of long-term de facto occupation rather than any formal legal recognition. Italian courts have at various points issued rulings addressing the occupancy status of the village, and eviction proceedings have been instituted on more than one occasion, though their implementation has been resisted, delayed, or suspended through a combination of community organization, public sympathy, and the practical and political difficulties of removing an established residential community from a site of recognized cultural significance. The community’s own founding statute asserted that the ruins were unowned and therefore freely available — a position that Italian property law has not recognized. The site’s cultural and heritage significance is broadly acknowledged, but this recognition has not translated into the formal legal framework that would clarify the residents’ position, and the situation continues to evolve through the Italian legal and administrative system.

How do the levadas of Madeira relate to the hydraulic traditions of the Hanbury Botanical Gardens?

The levadas of Madeira — a network of narrow open irrigation channels cut into the island’s rock faces and hillsides to carry water from the wet north-facing slopes to the drier terraced agriculture of the southern and western coasts — represent one of the most elaborate gravity-fed irrigation networks in the Atlantic world, constructed and maintained since the fifteenth century. Their underlying hydraulic principle — high-point collection of precipitation, long-distance gravity-fed distribution through channels, terminal delivery to cultivated areas at lower elevation — is closely analogous to the cistern-and-channel tradition of Ligurian agricultural terracing that underpins the hydraulic infrastructure of the Hanbury Botanical Gardens. Both systems exploit the vertical gradient of a steep, rain-fed landscape to distribute water without mechanical energy input, using the accumulated engineering refinement of agricultural communities working within the same basic physical constraint: more water falls at higher elevations, more cultivation occurs at lower ones, and the challenge is to move the water from one to the other by the cheapest available means. The similarity of solution emerged independently from the similar structure of the problem; there is no historical connection between the Madeiran levada tradition and the Ligurian cistern-and-channel tradition, and the convergence reflects the universal applicability of gravitational hydraulics as a response to the topographic conditions of steeply terraced coastal landscapes.

What practical lessons do Hanbury Botanical Gardens and Bussana Vecchia offer for heritage planners working with complex or contested sites?

The two sites examined in this article offer complementary lessons for heritage practitioners working with sites of informal occupation, physical complexity, or contested ownership. At the Hanbury Botanical Gardens, the institutional model — formal academic management, heritage listing, professional maintenance — provides the framework for sustainable stewardship but depends on continuous resource input and political will that cannot always be guaranteed for a site whose maintenance demands are high and whose revenue generation is limited. At Bussana Vecchia, the community model provides committed long-term physical presence and a constituency deeply invested in the site’s survival, but lacks the systematic oversight, documentation, and technical standards that formal conservation demands. The most productive reading of both sites is as evidence that heritage stewardship is a problem that admits of multiple partial solutions, each with distinct strengths and failure modes. For planners, the question is not which single model to choose but how to create governance frameworks that can recognize and actively support the strengths of community-driven stewardship — commitment, place-knowledge, atmospheric sensitivity — while introducing the systematic oversight and technical quality assurance that informal regimes alone cannot provide. Both sites suggest that effective heritage governance requires a willingness to work with the custodians who are actually present and engaged, rather than against them.
