Archaeological Complex of Medieval Walls

The Archaeological Complex of the Medieval Walls houses the remains of a defensive complex built in the late 13th century. It happened when Algeciras was under Marinid domain.

In 1379, the Nasrid Sultan Muhammad V carried out the destruction of the city and the walls. Then, the city was uninhabited until the arrival of new settlers from Gibraltar, in 1704. It is believed that at this time, with the resurgence of modern Algeciras, residents returned to rebuild the city from the Muslim fortress.

The ruins consist of a defensive wall of a hundred metres, four towers of the Late Medieval Ages and two smaller, whose origins are still unknown. A few metres from the defensive wall lies a mud rampart and moat six metres deep.  They were crossed by a bridge to the Tower Gate of Gibraltar or the Fonsario Gate.
