Historical sources indicate that the predecessor of the current Oberwerris Castle stood on this place already in 1284. The palace complex which stands here today consists of several buildings from different eras. The most important of them is the two-storey brick castle with sandstone trim, built at the junction of the 17th and 18th centuries. To the north of it there is a hut - the oldest building of the complex.
Inside Oberwerris Castle you can admire a fireplace dating to 1672, transformed into a Gothic arched window. There is a baroque garden near the gatehouse. The stables, adjoining the kennel, are to the east of the main house. Oberwerris Castle is used mainly for conferences and receptions. The training center of the Gymnastics Federation of the North Rhine - Westphalia land is also on its territory.
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.
