Hornburg Castle was first mentioned in a 994 deed as a property of the Bishopric of Halberstadt. In 1005 it was the birthplace of Pope Clement II. The fortress located on a limestone plateau served to control the northern border of the bishopric and the trade routes from Halberstadt to Braunschweig and Hildesheim. It was devastated by Henry the Lion in 1179 during his conflict with the bishop, an ally of Emperor Frederick I Barbarossa, who had the castle rebuilt.
