The castle-palace of Belalcázar is one of the most representative of the 15th century, when the nobility attempted to demonstrate its social and economic status.
Built entirely of stone blocks, Belalcazar preserves two enclosures: an outer barrier adapted to the irregularities of the land and reinforced with rectangular towers, and the inner rectangular castle-palace with eight towers, one at each corner and another in the center of each side. All eight towers are of average height except for the eastern and principal tower, which rises noticeably above the rest.
In the 15th century, some Renaissance construction was added to improve the accommodations of the palace, which were insufficient in the old principal tower.The castle was built by the magnate Gutierre de Sotomayor, grand master of Alcantara, with the benefices he earned from his various possessions. The castle later passed on to the houses of Benavente and Osuna. In 1811, during the War of Independence, French troops defended the castle against a siege by the duke of Wellington's British troops.The exterior of the fortress is almost entirely intact, but nothing remains of the interior structure.
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.
