The Alcazaba of Antequera is a fortress in Antequera, Spain. It was erected in the 14th century to counter the Christian advance from the north, over Roman ruins. The fortress is rectangular in shape, with two towers. Its keep (Spanish: Torre del homenaje, 15th century) is considered amongst the largest of Moorish al-Andalus, with the exception of the Calhaorra in Gibraltar. It is surmounted by a Catholic bell tower/chapel (Templete del Papabellotas) added in 1582. Connected to the former by a line of walls is the Torre Blanca ("white tower").
