Bellevue Palace
Kassel, Germany
Bellevue Palace (Palais Bellevue or Schloss Bellevue) in Kassel was built in 1714 for Charles I, Landgrave of Hesse-Kassel. Originally the building served as an Observatory. It became a residence, and then part of Bellevue Castle, which was later destroyed. Until its closure for structural reasons in 2009, the building housed a museum devoted to the Grimm Brothers, which has now moved to the Grimmwelt Kassel.
