Il paesaggio militare del XX secolo a Is Mortorius. La Sardegna tra storia e disegno

The Sardinian coastal landscape is historically characterized by a network of sentries built between the 16th and 20th centuries. This system consists of the imposing guard towers built during the Spanish and Piedmontese reign and bunkers and batteries designed in 1942-1943 to counter an imminent Allied landing. The bunkers, camouflaged by using materials from the area or with forms that recall functions other than military ones, are an important part of an architectural heritage currently under study for its recovery and valorisation, also within cultural itineraries. The area of Is Mortorius, in the coastal territory of Quartu Sant'Elena (CA), preserves many military structures from different eras. In addition to the presence of the nuraghe called Diana, reused during the Second World War as a rangefinder, the small promontory overlooking the sea hosts the ruins of a Spanish tower, numerous anti-aircraft stations, connected by underground tunnels, and some bunkers built with the use of reinforced concrete and lined with local stone and shapes that remind the nearby nuraghe. The proposed study, based on a historical analysis of the events that took place during the Second World War, provides for the application of integrated methodologies of survey and representation of architecture and landscape; UAV applications, aimed at the construction of a digital model of the context, direct and instrumental survey with laser scanners for a reading of underground routes, drawings from life through different techniques (watercolour, pencil and pen drawing) to grasp the character of the place and to promote, through the composition of a knowledge mosaic entrusted to history and drawing, a correct knowledge of the material and immaterial heritage of the wars of the twentieth century.
