The current baroque palace, Schloss Werneck, designed by Balthasar Neumann, was built in 1733–45 by Prince Bishop Friedrich Karl von Schönborn. For half a century it was, with Veitshöchheim, a summer residence of the Bishops of Würzburg.
Beginning in 1853, the palace was converted into a hospital for the mentally ill. The hospital is thus one of the oldest psychiatric institutions in Germany. In 1940, the approximately 800 patients were murdered on the orders of Otto Hellmuth, Gauleiter of Mainfranken, as part of the Nazi elimination of mentally ill and handicapped people, Action T4.
Today the grounds of the palace, including the Baroque garden and English-style park, may be visited, as may part of the palace, chiefly the chapel, which dates to 1744.
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.
