Affinities in the construction techniques of a unitary project: the coastal towers of the Asinara Island (Sardinia)

[EN] This study stems from the idea of highlighting the constructive affinities among the three towers of the Asinara Island, resulting from a unitary construction project. The research methodology identifies a multidisciplinary protocol based on a stratigraphic approach. With the aid of historical sources and petrographic and geochemical investigations, the sequence of the construction phases and stratigraphic units was identified for the towers. The results were compared in order to highlight common elements and significant differences in the typology and proportional relationships between the geometry and the constructive elements. The comparison also included material composition and masonry texture. The results highlight several similarities among the three towers and confirm the initial thesis: the imprint due to the unitary construction project was of major importance in terms of construction choices and binds the three towers in a common thread.Murru, S.
