The Leichtweißhöhle is originally a small natural cave and not much more than a large rock overhang, a so-called abri . The local shale is not suitable for karstification . There are no other caves.

The cave was forgotten until Wiesbaden gained international renown as a spa and the cave developed into a popular excursion destination. It represented one of the new attractions that were to be offered to visitors to Wiesbaden. The Wiesbaden Beautification Association expanded the cave in 1856. A second entrance was created, a room on the side and a niche padded with moss, which was declared as a place to sleep. The cave was also decorated accordingly, including old weapons and pictures. A romanticization followed . The Schwarzbach coming from the Rabengrund and passing the cave received an artificial waterfall and a wooden bridge was built to cross the stream. A viewing pavilion was built above the cave, and the access paths to the cave were equipped with railings and the cave entrance with a wooden porch. These changes were so extensive that the original state can hardly be recognized today.

In 1905 Kaiser Wilhelm II visited the cave with his wife.

In 1934 the Gestapo used the Leichtweißhöhle as a torture cellar .

With the decline of the Wiesbaden cure, especially after the end of the Second World War , the cave lost its importance and was closed. The outdoor facilities were badly affected by vandalism and lack of maintenance. The cave was often used as a shelter. In 1983 the entrance was completely renewed. Since then, the cave has been regularly opened to visitors every six months.”
