The Castello Maniace is a citadel and castle situated at the far point of the Ortygia island promontory, It bears the name of George Maniakes, the Byzantine general who besieged and took the city in 1038. Originally, one could only enter the castle over a bridge spanning a moat (now filled). A feature of the castle is the decorated portal. Today the castle is open to public and is a local tourist attraction in Syracuse.
The first fort was built here in 1038 by George Maniakes, a Greek general and later the Catepan of Italy, after he captured Syracuse from the Arabs on behalf of the Emperor Michael IV. Frederick II, as King of Sicily, had his architect Riccardo da Lentini rebuild it in 1232–1240. King Peter III of Aragon resided here with his family in 1288. From 1305 to 1536 the castle was used as residence by numerous queens of Sicily.
In the 15th century it was used as a prison. In the following century it was included in the fortification defending the harbour and the city. A huge explosion damaged it in 1704, after which it was renovated and adapted to the use of guns.
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.
