Little remains of the Alcazaba, or fortress, of the Alhambra, which dates from between the eleventh and fourteenth centuries. Originally built during the reign of the Zirid dynasty, it was enlarged by the Nasrids in the fourteenth century. The Alcazaba contained quarters and services for the military, baths, domestic architecture, and storerooms.
