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 Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.
The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.
The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
