Wauwilermoos was an internment camp and prisoner-of-war penal camp in Switzerland during World War II. Established in 1940, Wauwilermoos was a penal camp for internees, including Allied soldiers, among them members of the United States Army Air Forces, who were sentenced for attempting to escape from other Swiss camps for interned soldiers, or other offences. Together with Hünenberg and Les Diablerets, Wauwilermoos was one of three Swiss penal camps for internees that were established in Switzerland during World War II. The intolerable conditions were later described by numerous former inmates and by various contemporary reports and studies.
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.
