The Alcazaba of Antequera 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 (Torre del homenaje, 15th century) is considered amongst the largest of Moorish al-Andalus, with the exception of the Comares Tower of the Alhambra. 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').
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
