Bürresheim Castle is a medieval castle northwest of Mayen. It is built on rock in the Eifel mountains above the Nette. Bürresheim Castle, Eltz Castle and Lissingen Castle are the only castles in the Eifel region which have never been destroyed. It was inhabited until 1921 and is now a museum.
Built in the 12th century, Bürresheim was first mentioned in 1157 with its former owners, the noble Eberhard and Mettfried “de Burgenesem”. The castle consists of buildings constructed between the twelfth and the seventeenth century. Almost all of it is original, including the twelfth century keep, which is the oldest part. The castle was never taken or raised or slighted (unlike almost all other Rhine castles). It featured in the film Indiana Jones and the Last Crusade, in which it was called Brunwald Castle.
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.
