Stapelburg Castle was first mentioned in 1306 and the estates passed to the Prince-Bishops of Halberstadt in 1394.
The Stapelburg was built before 1306 by the Counts of Wernigerode to guard the military road that connected the counts' main ancestral castle with the imperial and mining town of Goslar. The castle was enfeoffed several times and in 1394 came into the possession of the Diocese of Halberstadt for a sum of 600 marks.
