Medina de las Torres Castle origins date back to the 14th-16th centuries. It was built on a low hilltop by the Order of Santiago in the 14th century as the headquarters of the Encomienda de Medina de las Torres.
In spite of having been restored on a number of occasions, this fortress is in quite a deteriorated condition. Even so, you can still appreciate the remains of the masonry ramparts, with a ditch and towers at the sides for the defence of this elliptically shaped castle. The entrance is on the southeast side, protected by two square towers. The main access to the interior was flanked by one circular tower and another which was semicircular. In this area there were storerooms, stables and a chapel, as well as a water cistern.
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.
