Fuentetétar Castle is a rural castle from the 12th and 13th centuries that is located next to the village or farmhouse of the same name, rising on the top of a high hill from which much of the surrounding lands is controlled, visually connecting with the castle of Jaén and with the castle of Zumel.
At present it is inhabited as a farmhouse, having undergone important reforms. Its keep, made of masonry, has practically disappeared. Some of its rooms are used as a stable for goats, among others. It presents numerous emergent remains from all eras.
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.
