The palace of the prince-bishops of Bamberg has been steeped in intrigue ever since a corpse found beneath the windows of the palace in 1815 turned out to be the body of Marshal Berthier, Napoleon’s chief of staff, who retired here after Napoleon was exiled to Elba. No one knows if Berthier was murdered or committed suicide. If you wish to step inside, you can join a guided tour (in German only) that shows off Gobelin tapestries, parquet floors, baroque furnishings, and possessions of these clerics with decidedly secular tastes. Upstairs, a branch of the Bayerische Staatsgalerie (Bavarian State Gallery) houses a few of the masterpieces collected by Mad King Ludwig; among them is Lucas Cranach’s almost surrealistic depiction of Abraham preparing to slay his son Isaac on God’s command, set against a German backdrop complete with medieval peasants. The romantic looking, rambling half-timbered Gothic structure next to the palace is the Alte Hofhaltung, the residence of the prince-bishops until the Neue Residence replaced it in the 17th century.
