The Stones Tell: The Dry Stone Walls of Salento, History and Resilience in the Landscape
Dry stone walls, characteristic of the Salento landscape, represent a tradition that has its roots in ancient times. These structures, built without the use of mortar, are an extraordinary example of rural architecture, a symbol of a past rich in history and culture. In this article we will explore the origins, evolution and current use of dry stone walls in Salento.
The first evidence of dry stone walls in Salento dates back to pre-Roman times, and the walls of this period have a structure of square blocks placed horizontally.
The local populations, the Messapians, began to use them to protect their crops from grazing, to mark the border between one property and another, as a small enclosure for animals (ncurtaturi), or they built them along the coast to protect crops from atmospheric agents.
The construction techniques were handed down from generation to generation, improving and adapting over time, and a real "craft" was born, handed down from father to son, the so-called "paritaru" ("parite" in Salento dialect means wall).
Currently the most significant evidence of these ancient walls is found in northern Salento, in the "Archaeological Park of the Messapian Walls", which extends for 150,000 m² to the north-east of the municipality of Manduria. Inside, large sections of the triple circle of walls that surrounded the city in the Messapian era are preserved.
During the Roman period, the practice of building dry stone walls became more widespread. Following the example of the civilizations that preceded them, the Romans adopted more than one dry stone construction technique (opus, in Latin), but the most widespread in Salento is the polygonal work (opus siliceum). The construction technique involves the composition of a rock bank arranged in two parallel rows of large stones, then two more rows of smaller stones converging upwards are added and the empty spaces are filled with other thinner material. The rows are then tied together with other larger stone slabs, this time inserted edgewise. In this case too, the spaces are filled with material. To finish everything off, the remaining cracks in the facades are closed by inserting stone chips. The Romans, expert engineers, recognized the effectiveness of these structures in containing the land and in delimiting agricultural areas.
In the Middle Ages, dry stone walls continued to be used mainly for the creation of terraces on hilly terrain, to prevent soil erosion and facilitate cultivation, and also to build rainwater channeling systems, improving the irrigation of fields. These structures were also very useful in animal breeding, and the projecting walls, in addition to enclosing their courtyards, were insurmountable by wolves, foxes and cattle herders, as well as ensuring the possibility of saving on labor for the care of animals, raising them in a semi-wild state.
During the Renaissance, a period of great expansion and innovation in many sectors, agriculture also underwent significant changes. This era, characterized by the rediscovery of antiquity and a growing interest in science and technology, profoundly influenced the way in which agricultural landscapes were managed and structured. In Salento, dry stone walls became even more widespread and vital to the agricultural economy, responding to new production and environmental needs. With the expansion of agriculture and the increase in production needs, these structures proved essential not only for the delimitation of land and the control of soil erosion, but also for harmonious integration into the rural landscape.
The twentieth century saw a partial abandonment of dry stone walls, due to the mechanization of agriculture and increasing urbanization. With the introduction of modern agricultural machinery, the way in which the land was cultivated changed radically, as heavy machinery required large and obstacle-free spaces to function effectively, and therefore many dry stone walls were knocked down or destroyed. This change also led to a loss of traditional cultivation techniques and the knowledge associated with the construction and maintenance of dry stone walls.
The increasing urban development and the expansion of residential and industrial areas also significantly affected the landscape of Salento, because with urban expansion rural areas were often converted into urban or residential areas, leading to the demolition of dry stone walls to make room for new buildings. Furthermore, many dry stone walls remained abandoned and in a state of decay, as rural communities moved to cities and peri-urban areas.
In the last decades of the twentieth century there was a change of trend, and there was a growing recognition of the cultural and landscape importance of dry stone walls. Historians, archaeologists and environmentalists began to highlight their historical and cultural value as an integral part of the rural heritage of Salento. Furthermore, people began to understand how much dry stone walls contribute to the beauty and uniqueness of the Salento landscape, offering a distinctive element that enriches the view and understanding of the territory.
All this has led, nowadays, to a renewed interest in their conservation, with significant consequences. Today, in fact, the dry stone walls of Salento are recognized as a cultural heritage of great value. In 2018, the art of dry stone walls was inscribed on the UNESCO list of intangible cultural heritage, a recognition that has given new life to conservation and restoration efforts. Traditional techniques are now taught to new generations, ensuring the continuity of this ancient art.
Furthermore, dry stone walls are increasingly appreciated for their positive environmental impact. In addition to preventing soil erosion, they promote biodiversity, offering refuge to numerous species of flora and fauna, a true "ecological corridor" that allows the transmission of a microfauna rich in insects, reptiles and amphibians that operate spontaneously, in synergy with human agriculture, to maintain a healthy and parasite-free environment. The interstices become their home and hiding place. The dry stone walls, with the spontaneous vegetation that grows between the stones or close to the walls themselves, constitute an important ecosystem. In their correspondence a particular microclimate is created, favorable to Mediterranean plants that can thus, thanks to the greater availability of water, overcome the summer crisis.
In particular, with regard to this last aspect, the project “L’Orto dei Tu’rat" – Storia di un’acqua spremuta dalla pietra” is worthy of note, part of the cultural/agricultural/ecological park in Ugento (Lecce). “L’Orto dei Tu’rat currently extends over an area of 16,000 m2, and is a type of barrier/drainage of very ancient origins, dating back to about 9,000 years ago and adopted in the Middle East. Since 2008, an apparently banal construction, modeled with dry stone in the shape of a crescent and arranged in such a way as to capture the humid south-west winds in its concave part, has caused the water contained in them to condense on its sloping surface. For the agricultural populations of the Mediterranean areas characterized by desert climates, with significant temperature variations from day to night, it was an effective irrigation system for the vegetation grown immediately at its feet. It is an excellent example of bioclimatic architecture, which exploits passive phenomena, avoiding the waste of non-renewable energy.
Even in the tourism sector, dry stone walls play a crucial role in preserving the authenticity and charm of the Salento landscape, acting as a magnet for visitors looking for a genuine experience. These ancient structures, which dot the territory with their rustic elegance, offer a glimpse of local tradition and culture, attracting tourists eager to explore and appreciate the pristine beauty and rich history of the region. Dry stone walls not only visually enrich the landscape, but also evoke a sense of continuity and connection with the historical roots of Salento, making each visit a journey through time and an immersion in the authentic culture of the territory.
The dry stone walls in Salento are much more than simple stone structures; they represent an authentic symbol of resilience, ingenuity and creativity of local communities. These structures, born from the expert hands of artisans who worked
with stones collected from the fields, are witnesses to a thousand-year-old tradition that has been able to adapt and thrive through centuries of historical and social transformations. From their ancient origins, when they served to delimit the land and manage natural resources, to the present day, dry stone walls have been able to maintain their function and their charm intact. Each stone, laid with care and precision, tells a story of adaptation and harmony with the environment, reflecting the ability of local populations to respond to the challenges of time without compromising their essence.
"Ogni petra azza parite" (every stone contributes to building a wall), or "Every stone has its own story", is a Salento expression that encompasses the essence and profound meaning of stone structures. This dialect phrase, steeped in popular wisdom, does not limit itself to describing a material aspect, but evokes a deeper connection between the stones and the stories they tell.
Today, as in the past, these walls continue to be much more than simple elements of the landscape: they are custodians of the historical memory and culture of Salento, uniting the past with the present and contributing significantly to the preservation of the identity and beauty of a unique territory. Their silent but powerful presence enriches the landscape, transforming it into a stage where history, culture and nature intertwine in a fascinating tale of resilience and continuity
