Ruhethal Castle was built in 1150 in the Döllnitztal including the chapel and was the former bishopric of the Meißen diocese. At the place where the castle stands today, there used to be a moated castle. Meißner bishops carried out further modifications in 1261 and 1341. The mighty 40-meter-high tower, which was built under Bishop Nicholas I in 1380, is characteristic of the view of Ruhetal Castle .
Around 1590 the castle was the resting place of Bishop Johann IX. from Haugwitz . Today the Free State of Saxony is the owner. A development association from Mügeln develops usage concepts and takes care of the maintenance of the castle.
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.
