At the edge of a rocky, bushy trough opens the imposing, wide mouth of the cave, which leads hole-like obliquely into the depths. The cave is 30 m deep and has the size of a mediocre church, as Karl Kugler wrote in his 1868 printed book about the Altmühlalb. A secure staircase with 80 steps opens up the visitors to the cave, in which due to the coolness and the darkness in the inner wool jacket and flashlight should be taken.
The cave is a collapse of subterranean karst cavities created by the dissolution of the limestone in carbonated water and the leaching of streams of water flowing through it. In fact, from the hall-like room at the lowest point of the cave, two spill fireplaces, almost still buried but still visible, lead further into the interior of the mountain. In a report on the cave from the year 1799, it says: On the floor are all sorts of bones of animals everywhere. However, this suggests less an animal sanctuary, rather the cave was a death trap for animals or garbage pit for food leftovers of humans. As a place of residence for humans, the cave had certainly been used repeatedly. This is supported by potsherds from the Hallstatt period and medieval ceramic remains, which were found in large numbers. Broken human bones indicate that the cave served as a prehistoric sacrificial shaft. By the way, caves are by no means only death-pits, in them still many life stirs. They are wintering grounds for several bat species (eg mouse ear, long-eared, horseshoe nose), which are highly endangered in their population. Other animals that can be found in the cave are the cave spider (Meta menardi) and moths.
