The Manningaburg castle in Pewsum dates back to the year 1458 and was originally - as the name suggests - the headquarters of the chief family Manninga. However, in 1565 the castle was sold from Chief Haiko Manninga to Count Edzard II Cirksenas. Unlike most castles in Ostfriesland, Manningaburg is open to the public and houses a museum dedicated to the chief and castle history. In the ceremonial hall of the castle, you can get married in a civil ceremony.
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.
