In this article we deal with the unique coastal defensive belt that the city of Malaga has in Nasrid times, about the origin of it and its process of building as well as its functionalities that exceed the purely defensive ones. The first constructions aimed at defending the city from the sea correspond to the dynasty, with the construction of the alcazaba and the defensive fence of the medina, as well as incipient atarazanas, a cast of works of political propaganda. The Almoravid and Almohad empires do not stand out for the execution of new plant works, but rather for maintenance, adequacy and repair work. Its peak will be reached during the Nasrid sultanate, with the buildings of the castle of Gibralfaro, a terrestrial coracha, the castil of the Genoese and the atarazanas, all of them distributed and adapted with great skill to the coastal topography, as well as also by suggestive refortification works. All this reflects the various political and economic situations that aretransformed throughout the Islamic period during the caliphate, as the caliphate and the Nazarí headquarters, of which Malaga is the second city in importance and its main port.

Our methodology has taken into account the contributions of textual sources, historiographic sources and, above all, archaeological actions.
