Between the 1980s and 1990s, the Almoina site in Valencia was excavated by the SIAM (Municipal Service of Archeological Research) and also, in the following decade, the subsoil of the Almudín and the San Luis Beltrán square. In these surveys, remains of the fortifications of the Alcazar were found, as well the royal cemetery and the palatine dwellings that were presumably inside the enclosure. However, the excavation has been partial and not allowed us to understand the functioning of the complex.
The ribat in Bouna (present day Annaba), also called the Fusula Ribat, dominates the promontory of the hill with the same name and overlooks the port of the town. This defensive structure, whose typology dates from the Fatimid period, belonged to a chain of ribats marking Islamic territory along the length of the Mediterranean coast. It was concealed under the Sidi Boumerouane Mosque. Thus, through a series of transformations, the site became a veritable military-religious complex.
