Rocca, a medieval castle with quadrangular bastions bounded by a canal with drawbridge, was built in 1124. It was the fortress of the noble family Scaligeri, who became the Lords of Verona. It was rebuilt several times and it was used by the Austrians as barracks in the 18th century. It is frequently the seat of cultural activities, especially during the summer months. It hosts the Civic Museum and of the Picture Gallery.
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.
