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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
