Estepa castle was known in the Islamic period as Hisn Istabba, and was taken by Spanish king Fernando III on 15 August 1241.
The city walls that still surround the old town on the San Cristóbal hill were first built in the tenth century by the Moors, renovated by Almohad invaders in the twelfth, and again reconstructed when Estepa fell to the Christian Order of Santiago in the thirteenth century. The keep inside the walls was built against attacks from Granada in the fourteenth century, and at 26 metres offers sweeping views of the town and surrounding countryside.
A defensive tower built by Lorenzo Suárez de Figueroa, Master of Santiago, it carried out defensive and logistical functions, measuring 26 metres high by 13 metres wide. On clear days, you can see Sierra Nevada from the roof.
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.
