The wall of the Andalusians delimits the southern part of the Medina. When it was built at the beginning of the seventeenth century, it bordered the part where the Moriscan refugees settled in the southern part of the future Almohad city, which was actually uninhabited and consisted only of fields ².
More than 1.4 km long, the height of the wall varies between 4.9 m and 5.5 m for an average thickness of 1.65 m.
The wall is composed of 26 barlong towers and is fortified with a wall-walk, of a width between 1.3 m and 1.5 m, protected by a parapet pierced with loopholes.
The wall ends, to the east, Borj Sidi-Makhlouf, a bastion of round shape pierced with arrowslits and cannon embrasures, adjoining a tower.
