Schloss Brake was a former residence of the Counts of Lippe. The first castle was built after 1190. In 1447 it was conquered and burned during the feud. The current appearance dates mainly from the 1570-1587 when it was modernized in Weser Renaissance style. In 1663, Count Casimir of Lippe-Brake rebuilt the east wing to its present form. Since 1986 the Weser Renaissance Museum has been located in the 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.
