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.
The territory of the Roman countryside in the Late Middle Ages was extended from the city of Rome to 40 miles in the Suburb, between the coasts of the Tyrrhenian Sea, the Albani Mountains, the Lepini Mountains and the course of the Tiber.
At the beginning of the nineteenth century, even if the phenomenon of running war had subsided, the watch towers still had an active role in controlling the coasts of Southern Italy. Under the French administration some of them were assigned to customs posts, others continued to report the corsair boats always ready to carry out incursive actions. Merchant ships, fishermen and peasants were still struck by the devastating Turkish-Barbarian cruises, but also by corsairs armed by the British in an eternal struggle against the French.
