Château de Tancarville was built in the 11th century by Raoul, the chamberlain of Dukes of Normandy. In the 12th century the square tower was built with 1.65m thick walls. In 1418 at the time of the conquest of Normandy by Henry V of England, the title of Earl of Tancarville was given to John Grey. After the Hundred Years War the Harcourt family restored the castle. The ballroom was built in 1468. In 1709 the castle was partially rebuilt by the Count of Evreux. After 1789, the castle was plundered and partly burned. In the 1960s , the castle served as a summer camp for children.

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.
