In 1931, Carl Schuchhardt suggested, through advances in soil research, that this was incorrect 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.
