The Königsburg is a ruined medieval castle southeast of Königshütte, a village in the borough of Oberharz am Brocken, in Harz district in the German state of Saxony-Anhalt.

They lie at a height of 460 metres above sea level on the edge of a wooded plateau and offer a good view of the Wurmberg and the Brocken, the highest mountains in Lower Saxony and the Harz respectively.

When Paul Höfer carried out extensive excavations in the years from 1898 to 1901, he assumed he had discovered the long sought after palace (Pfalz) of Bodfeld and produced several publications about it.

In 1931, Carl Schuchhardt suggested, through advances in soil research, that this was incorrect[1] and, a little later, this was confirmed by Paul Grimm, who was able to establish that the finds, especially the pottery, were not older than the 13th century.

Although the results of this research from the 1930s have been consistently acknowledged within the scientific community, Königshütte still advertises today that the Königsburg is the Bodfeld hunting palace and one of the most significant historical sites in the Harz.
