Throughout history, Algerian coastal towns have been subject to various threats by sea, which has resulted in different types of fortification works. Their variety depended on their period of construction, the materials used and the genius of the place. In Algiers, these structures of fortifications vary between fortified castle, ramparts, watchtowers, etc. However, this historical legacy is, day after day, threatened with disappearance for lack of support.
This paper offers suggestions for the knowledge of fortified centres of the Tyrrhenian coast of Northern Calabria, through a critical reading of ancient graphic representations of this territory. The exegetical reading of these ancient landscapes has been supported by the notes extracted from literary sources and data deduced from analytical procedures conducted on the assets.
