Övraby Church was built in the 1100s. The porch and tower were added in the 15th century. The church contains some interesting frescoes, whitewashed over after the Reformation and only rediscovered at the beginning of the 20th century. Experts have dated these to the 12th century, making them some of the oldest surviving church frescoes in Scandinavia. The pulpit and altarpiece are both from the early 17th century.
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.
