important bridgehead toward the east, the city of Otranto was provided since the antiquity of defense systems and fortified works. The siege suffered by the city in 1067 seriously damaged the fortress that was repaired and reinforced a few years later at the behest of Roberto il Guiscardo. The reconstruction promoted in 1228 by Frederick II of Swabia instead remain evident traces of the tower of the median body cylindrical, incorporated in the bastion at the tip of the lance, and in curtain walls of the north-east. An analysis of the undergrounds suggests that the castle was set to a plant with a central core with quadrangular, scanned at the corners by cylindrical towers.
After the sack of Otranto In 1480, the year in which the whole South of Italy was the object of the Turkish attack, the castle had to be rebuilt, which he did Alfonso of Aragon, Duke of Calabria. At the end of the century, when the city was given as a pledge to the Venetians, the structure was further enhanced with the addition of artillery and mortars. The Aragonese phase there remain only a tower and part of the walls. The current appearance of the small fortress it owes to the Spanish viceroy, who made it a true masterpiece of military architecture. The two polygonal bastions added in 1578 on the side facing the sea, inglobarono the preexisting aragonese bastion.
Today the castle of Otranto has a pentagonal plan, surrounded by a large moat and punctuated by four towers, three circular in carparo and one with the tip directed toward the sea. On the fifth side, discovered, opens the drawbridge. The fortress otrantina inspired the first gothic novel of history, the castle of Otranto, written by Horace Walpole in 1764.
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.
