All the mentioned conquers and occupations testity that the city, together with Amantea and Squillace, had a fundamental strategic importance for the dominion of the Region. This was due to its topographic position projecting towards the sea just like the bottom of a ship, with a perimeter falling perpendicularly into the sea waters from a hight of 40 mtr. And with the shoulders linked to the hinterland by an easy to block strip. For its predefence and its presence at sea, Tropea became a contested stronghold for the control of the Tirrenian side of the Region, and a reliable point for an eventual getaway. Therefore the walling works done to complete the natural defence system were of little importance. We have no records of how and when these works were carried out and completed.
