Valleberga Church is the only known fortified round church in Scania. It was built of limestone in the middle of the 12th century. A reason for the building of the round church was that the master mason of the church, Carl Stenmester, also built churches on Bornholm, where round churches were common. The font was cut by the master of Tryde and shows one of the legends about Saint Peter and Paul of Tarsus.
In 1791, the round church was demolished and extensions were made to the north, west and south. These extensions were demolished in 1908-1910 when the round church was restored and a large cathedral-like extension was made to the west, including a new tower.
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.
