Teufelsloch

The large oval cave entrance leads after a short distance to a large, north-facing opening in the rock that is reminiscent of a panorama window. The origin of the opening is unclear and could be due to a ceiling or wall collapse. The origin of the cave could be founded in the quarrying of scouring sand. On the northern rock wall of the cave, the so-called Rittertreppe leads up on the outside.

The legend Der Kuhstall an den Zinnen surrounds the origin of the large northern opening. According to it, a shepherd named Ulrich is said to have grazed his herd of cows and bulls at the Helsunger Bruch when he was surprised by a summer thunderstorm. In his hurried search for a sheltered place, a little man appeared to him, offered him advice and led him to the cave. When the shepherd had driven the animals into the cave and wanted to thank the little man, his form changed and the little man became the devil and rolled a large stone in front of the cave entrance, so that the herd and its shepherd were trapped. The bulls then became wild and ran against the rock wall for hours, until finally the rock on the northern side was pushed away and the window that still exists today was created. Ulrich was then able to flee and fetched help from Timmenrode. When he returned, the devil and the stone in front of the cave entrance had disappeared.

In 2016 the Teufelsloch was a filming location for the German fairy-tale film Das singende, klingende Bäumchen.
