Bruch water castle was built in the 14th century. From that time, the entrance side with the gatehouse, the five-story corner tower, and the round tower at the other end have survived. Originally, the castle was owned by the Lords of Bruch, then it was granted as a fiefdom to the Lords of Daun. It returned to the possession of Trier in 1539.
The complex is now privately owned. In 2023, a beer garden was opened in the courtyard of 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.
