From the countryside to the cliffs of Santa Maria di Leuca, a network of stones tells the story of agricultural labour, ancient boundaries and a heritage at risk of disappearing.
Some landscapes can only be understood by learning to read their details. In Salento, one such detail is a line of carefully stacked stones, seemingly simple, crossing olive groves, following the edges of footpaths, descending slopes and, in some places, appearing to guide the eye all the way to the sea. These are the dry-stone walls: one of the most distinctive and, at the same time, least understood features of Salento’s rural heritage.
They can be found along country roads, around masserie, beside cultivated fields and even on the slopes leading down towards the Adriatic and Ionian seas. Sometimes they are low and irregular, almost indistinguishable from the exposed bedrock; elsewhere, they form precise boundaries, built stone by stone with a skill that required no written plans. Some bear the marks of recent repairs, while others seem to belong to a distant past that is difficult to reconstruct.
It is precisely this apparent simplicity that makes them extraordinary. A dry-stone wall is not merely a fence: it is the result of a long relationship between people, stone and land.
Before the landscape, there was labour
To understand the origins of these structures, we must return to a basic necessity: making cultivable land out of a terrain that was often difficult, stony and covered by a thin layer of soil.
Limestone emerged during the clearing and cultivation of fields and had to be removed to make room for crops. Throwing it away would have meant wasting a resource; piling it along the edges, by contrast, solved several problems at once. The heaps gradually became boundaries, the boundaries developed into walls, and the walls became an integral part of agricultural organisation.
They separated properties, kept livestock out of cultivated fields, protected crops and helped retain soil on exposed slopes. Where the terrain was uneven, they contributed to the creation of terraces; where rainwater tended to concentrate, a properly built structure could help drainage and reduce soil washout.
This was no minor task. It required experience, an ability to recognise suitable stones, an understanding of slopes and a precise knowledge of the balance between weight and interlocking pieces. In Salento, the knowledge of traditional builders, known in some areas as paritari, was passed down through practical apprenticeship, by observing and working alongside experienced craftsmen.
The technique required no mortar: stability depended on selecting, positioning and fitting the stones together. Each piece had to find its place within the whole. It was a fundamental principle, almost a lesson in architecture born from limited resources and a deep understanding of the material.
How old are Salento’s dry-stone walls?
This is one of the most fascinating questions, but also one of the most difficult to answer. There is no single date that applies to every dry-stone wall in Salento. Many structures have been repaired, raised, dismantled and rebuilt several times; ancient stones may have been reused in more recent constructions. The building technique alone is therefore insufficient to establish when an individual wall was constructed.
Archaeological research, however, is showing why it would be wrong to regard all these structures as recent.
A particularly important reference is the study by Paul Arthur, an archaeologist at the University of Salento, entitled The Archaeology of Dry-Stone Walls in Rural Contexts, published in Studi di Antichità. The author examines the archaeology of field walls in southern Italy and stresses that these structures have often been overlooked because they are considered ordinary landscape features. Yet they can preserve valuable information about property boundaries, agricultural organisation and social and economic change.
The investigations discussed in the study provide concrete examples. At Supersano, in Salento, a section of dry-stone wall associated with pottery finds has been tentatively attributed to the eighth century AD. Another significant case is the so-called Limitone dei Greci, a large stone structure in southern Apulia whose chronology has been investigated through radiocarbon analysis of associated organic material, producing dates ranging from AD 670 to 880.
These examples do not prove that every dry-stone wall in Salento dates back to the early Middle Ages, nor that the walls visible today necessarily retain their original form. They do, however, demonstrate that this stone landscape may preserve evidence far older than its everyday appearance suggests.
The scientific reference is particularly valuable because it distinguishes between the long history of the building technique and the archaeological dating of individual structures.

Stone as an archive: from fields to ancient routes
A wall can reveal far more than might first appear. Its alignment may suggest an ancient boundary; a gap may indicate a passage for livestock or an entrance to a plot; a series of parallel walls may reveal a terracing system or an earlier arrangement of cultivated land.
This is why dry-stone walls should be studied alongside rural roads, masserie, cisterns, pajare and the traces left by agricultural activity. To consider them in isolation would mean losing an essential part of their history.
Historical maps and cadastral records can also help reconstruct changes in the territory. Comparing older maps with present-day ones may reveal, where sufficient documentation survives, the persistence of certain boundaries, former routes and changes in the division of land. Such work requires careful comparison: the appearance of a wall on an old map does not, by itself, establish its date. However, written records, cartography, field surveys and archaeological evidence can together provide a more accurate account.
Salento also preserves numerous traces of very ancient human occupation. Dolmens, menhirs, specchie, settlements and historic routes document the different ways communities have inhabited and organised the peninsula. These features do not all belong to the same period or serve the same purpose. It is therefore important not to confuse prehistoric megalithic monuments with agricultural walls, even when both share the use of unmortared stone.
Their connection is primarily cultural and territorial: they testify to a longstanding familiarity with stone and an ability to adapt the landscape to the needs of everyday life.
Where the walls meet the sea
Along the coastal stretch between Tricase, Corsano and Santa Maria di Leuca, this story takes on a particularly evocative form. Here, stone does more than define the geometry of fields: it accompanies ancient paths, follows limestone ridges and encloses plots overlooking one of the Mediterranean’s most spectacular landscapes.
From the sea, when navigating along the coast in conditions that allow the mainland to be observed, it is possible to recognise stretches of terraced countryside and traces of traditional rural organisation. The walls blend into the Mediterranean vegetation, following the contours of the land and breaking off where exposed rock and steep slopes emerge. They are not always easy to distinguish from a distance, but where the landscape opens up, they become part of a striking composition: pale stone, green scrubland, cultivated plots and the blue sea.
This view takes on even greater meaning when seen from the mainland, along routes connecting the hinterland with the coast. Within the Costa Otranto–Santa Maria di Leuca and Tricase Woods Regional Natural Park, the network of paths still preserves traces of ancient connections between villages, farmland and the shoreline.
The N’Zepe–Bortoli and Scalapreola tracks, in the Corsano area, are particularly significant examples. They cross the limestone ridge, pass between dry-stone walls and terraced fields, and reveal the relationship between agricultural activity and the coast. Some historic routes were also associated with moving flocks and collecting sea salt, a valuable resource used for food preservation and local exchange.
In this landscape, the boundary between nature and human labour becomes blurred. The walls do not erase the shape of the land but follow it; they do not conceal the rock but turn it into something useful. They belong to a territory where human presence has left deep marks without entirely severing its connection with the natural environment.
An architecture that also protects biodiversity
The role of dry-stone walls extends beyond agriculture. Gaps between stones, sunlit surfaces and damp corners provide microhabitats for small organisms, while vegetation growing along the walls can help maintain ecological connections across the landscape.
These structures can also improve drainage and limit erosion, particularly when properly integrated into the terrain and maintained in good condition. Their effectiveness is not identical everywhere: it depends on their location, construction and maintenance. Nevertheless, their disappearance can affect not only the appearance of the landscape but also the relationships between soil, water, vegetation and wildlife.
This importance is recognised internationally. In 2018, UNESCO inscribed the art of dry-stone walling on its Representative List of the Intangible Cultural Heritage of Humanity, acknowledging the value of knowledge and techniques passed down through generations. The recognition concerns a tradition shared by several countries and regions, not Salento alone.
From this perspective, stone is more than a building material. It is a local resource that, without mortar, can be transformed into adaptable, repairable structures closely connected to the characteristics of a place.
A wounded landscape: abandonment, Xylella and the loss of maintenance
Over recent decades, Salento’s rural landscape has undergone profound changes. Shifts in agricultural activity, the abandonment of some plots, the decline of manual labour and the loss of traditional skills have left many dry-stone walls without maintenance.
When a stone becomes dislodged in a critical section, when water accumulates behind an unstable portion or when vegetation disrupts the interlocking stones, deterioration can gradually spread. The collapse of one section breaks a boundary, creates an opening and leaves the ground more exposed to erosion.
The crisis caused by Xylella fastidiosa has made the fragility of the agricultural system even more evident in many parts of Salento. The loss of numerous olive trees and the resulting economic and management difficulties have also affected the relationship between communities and their land. It would not be accurate to attribute the deterioration of every wall to the disease: abandonment and decay have different causes, often accumulating over time. The phytosanitary crisis has, however, helped reveal how much the survival of built heritage depends on the vitality of the countryside.
The issue, therefore, is not simply about replacing a few stones. It concerns the conditions that allow a territory to remain inhabited, cultivated and cared for.
Masserie and communities: care as a shared responsibility
In Salento’s landscape, masserie offer a privileged vantage point. These historic agricultural estates are places where the region’s farming heritage can continue to engage with the present through production, hospitality, traditional knowledge and landscape protection.
When a farm restores a wall, when an agritourism business preserves the historic boundaries of its land, or when a community works to keep an ancient path accessible, it is doing more than improving the appearance of a property. It is helping preserve a part of collective memory.
Restoration, however, requires care. An old wall should not be dismantled and rebuilt without assessing its history, nor turned into a concrete fence that erases its original construction technique. Maintenance should respect local materials, traditional stone placement, permeability and the structure’s function, involving experienced craftspeople wherever possible.
Public authorities can also play a decisive role by supporting training for traditional builders, promoting surveys and inventories, enhancing rural paths and integrating wall conservation into agricultural and landscape policies.
Rediscovering the value of what seems ordinary
Perhaps the future of dry-stone walls also depends on how we look at them. For a long time, they were regarded as unremarkable features of the countryside, humble works that did not deserve the same attention given to churches, palaces or archaeological monuments. Yet precisely because they are so widespread and familiar, they tell a story that monumental architecture alone cannot convey: the story of people who transformed the land through repeated, often anonymous gestures across many generations.
When standing before a dry-stone wall, especially along a path descending towards the sea at Leuca, it is worth pausing to look more closely. Each stone may be the result of ancient labour; each alignment may preserve the memory of a boundary; each repaired section may tell the story of a craft that has survived.
We do not know how many of these walls have endured for centuries without being rebuilt, nor can we assign them a precise age without investigation. But we know that their value does not depend solely on the date of their construction. It lies in the history they preserve, the function they continue to perform and the possibility of keeping them within the landscape.
Salento is made not only of coastlines, villages and monumental architecture. It is also made of this quiet network of stones, capable of connecting farmers’ labour with community memory, the inland countryside with the sea, and history with our responsibility in the present.
To preserve this network is to recognise that a landscape is not an immobile backdrop to admire, but a living heritage to understand, maintain and pass on.
