History+
Badenburg Palace was constructed between 1718 and 1722 under the direction of Joseph Effner. It served as a bathing retreat, thus pioneering European architectural history. A restoration in 1983 and 1984 reinstated the original wooden shingle roof and the ocher-yellow facade color. On this occasion, a ceiling fresco by Jacopo Amigoni, destroyed in 1944, was replaced by a copy by Karl Manninger.
