Schloss Wilhelmshöhe is a palace located in the Bergpark Wilhelmshöhe in Kassel, Germany. As King of Westphalia, Jérôme Bonaparte renamed it Napoleonshöhe and appointed his Head Chamberlain Heinrich von Blumenthal as its governor, with instructions to supervise extensive renovations.
After the Franco-Prussian War, the Prussian King offered the defeated Emperor Napoleon III accommodation there. From 1899 to 1918 Wilhelmshöhe was the summer residence of the German emperor Kaiser Wilhelm II. In 1918, after the defeat of Germany at the end of World War I, Paul von Hindenburg organized and led the withdrawal and demobilization of the German troops there. The buildings were substantially destroyed during the Second World War.
