According to the legend, there were escape tunnels emanating from the castle hill,” says Wasmeier. He and a few friends decided to search for the tunnels. They dug and drilled, day in and day out. “In the end, the only one still digging was Rudi Eichschmied — every evening, sometimes in the moonlight,” says Wasmeier.
The man finally came across an underground cavity.
It led to a unique gallery with walls made of sand. Initially the tunnel went down vertically for 4 meters, and then it continued in a zigzag pattern. There was a narrow “Schlupf” section at the end of the labyrinth. It reminds the researchers of a vagina.
