This study focuses on the evolution of dry-stone techniques applied to the construction of enclosures in Corsica and Tuscany. Starting from the 5th millennium, the presence of enclosures has been observed in the Western Mediterranean basin. Used to enclose an area with various functions between the Middle Neolithic and the Iron Age, the enclosure can be a ditch, a bank or a dry-stone wall, as in Corsica. With the aim of applying the methodology of study of the Corsican enclosures to those of Tuscany, thegeographical framework of this study was extended to include all Tuscany.
