Château du Haut-Kœnigsbourg is a medieval castle located in the commune of Orschwiller in the Bas-Rhin département of Alsace, France.
Located in the Vosges mountains just west of Sélestat, situated in a strategic area on a rocky spur overlooking the Upper Rhine Plain, it was used by successive powers from the Middle Ages until the Thirty Years’ War when it was abandoned.
From 1900 to 1908 it was rebuilt at the behest of the German Kaiser Wilhelm II. Today it is a major tourist site, attracting more than 500,000 visitors a year.
