Probably built in 837 by Orso I, the Monte Sant'Angelo Castle has bastions of different ages. The most ancient part, called Torre dei Giganti ('Giants' Tower') is a pentagonal tower 18 m-high, with walls 3.7 m thick. The first documents on its history dates back to 979; later, it was the residence of Rainulf I of Aversa and the Robert Guiscard, who built the Norman Tower and the Treasure Hall.
Emperor Frederick II restored the construction to use it as residence for his mistress Bianca Lancia, while under the Angevines it was used mainly as prison. Later, from 1464 to 1485, the fortress was the residence of the exiled Albanian condottiero Skanderbeg. The castle was largely rebuilt in the late 15th century by Ferdinand I. According to a legend, the castle is currently home to the ghost of Bianca Lancia, whose sighs can be heard especially in the winter time. Today the castle is used for exhibitions.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.
