Le torri costiere della Sardegna. Metodiche per la conoscenza e la conservazione

This research focuses on the system of Sardinian coastal towers. With reference to these structures, it aims to investigate construction features and materials, with special emphasis on masonry techniques. Given the large number of towers, the study was organized in nine homogeneous districts, taking care to safeguard the specificity of the system. With the aim to evaluate several aspect of the topic, a multidisciplinary and integrated protocol was adopted. The towers have been studied from a historical, architectural, typological, technical and mineralogicalpetrographic point of view, based on a stratigraphical approach. Through cataloging and realization of a GIS, it was possible to establish a dynamic and “multi-layer” comparison among the obtained results and then to deduce a critical synthesis. The multidisciplinary approach, integrated by innovative technological tools (like photomodeling techniques and GIS), reveals a methodology that could be used in other contexts and a larger scale. Furthermore, the acquisition and systematic cataloging of data on masonry techniques included in a well-defined and documented chronological context could be a valuable tool for conservation projects and provide important references to chronologically define architectures from the same age, which are not easily datable.
