Schloss Wickrath was built between 1746 and 1772 by count Wilhelm Otto Friedrich von Quadt. The Baroque palace was built to the foundations of late medieval water castle. The original castle was demolished in 1859 by the Prussian administration. The current ensemble of buildings in the park, the Baroque west and east wing and the so-called Landstallmeisterhaus, the residence of the former stud master were built in 1875. The park has the shape of a coronet of a count of the Holy Roman Empire.
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.
