It lies in the lower Muschelkalk and contains rich stalactite ornaments such as slender and cone-like stalagmites and sinterflags, sinterterraces and crystals.

It was adapted for high numbers of visitors, with a large parking lot at the foot of the cave, including for tourist buses.

[4] The cave owes its discovery to chance in a limestone quarry: On December 13, 1971, a larger cavity was drilled in preparation of a blasting.

The press was informed how preliminary explorations revealed the beauty of a natural monument, unique in southern Germany.

Because the cave was particularly large and beautiful, and the dripping stones had a great variety of forms, it was found worthy for preservation and development.

The explosions in the quarry resumed at a minimum distance of 50 meters to the cave and an important employer of the municipality remained.

Only barbed wire guards above and below the entrance and an additional state police patrol service each night succeeded.
