wings of the castle. From 1 October to 30 April the hibernating animals must not be disturbed. In one vault there is a stone well, several metres deep. The underground cellars are so extensive that, on one occasion, two children that had strayed into them had to be rescued by the emergency services. According to oral tradition there were also underground escape tunnels to Lauenstadt and the Bishopric of Hildesheim. The ramparts still exist to the northwest, north and northeast.
