taken from wikipedia:
The six tombs are located in a forest near Tangeln and Mellin. After older investigations by Johann Friedrich Danneil (1843), Eduard Krause and Otto Schoetensack (1893) as well as Wilhelm Blasius (1904) there were originally at least two more tombs (tomb 2 and tomb 3). In a new recording in 2003 of these, however, no traces were found. According to an inhabitant, these seemed to have been destroyed by the new forest owners in mid-1990s. In return, however, another tomb was discovered in 2006, which had not been mentioned by the researchers of the 19th and early 20th centuries.
