Wildenfels Castle was built in the late 12th century. From 1602 to 1945 it was owned by Solms-Wildenfels counts. Thanks to its many cultural treasures, the castle is today a national attraction at the foot of the Erzgebirge mountains. These include the castle gallery, banqueting hall, wedding room, former count’s library and various museum rooms. Another highlight is the “Blue Salon”, which was named after its wall decoration of precious blue silk tapestries from the early 18th century.
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.
