The cultural cave "Hohler Stein" in Rüthen-Kallenhardt was formed over millions of years by the Lörmecke stream, which also gave its name to the nature reserve in which the cave is located.
The rock massif of the "Hohlen Stein" (hollow stone), washed out by tributaries of the Lörmecke in millions of years of geological history, rises southwest of the village of Kallenhardt in a particularly charming landscape. During excavations in the thirties of the 20th century, finds of human settlement and activities from different development epochs since the last ice age were discovered in the two cave areas.
Some traces and artifacts even go back to the migratory and settlement phases of the time around 10,000 B.C. Some excavation objects that have not been clearly clarified or remain mysterious to this day and their unusual finding environment have also surrounded this cave with mysterious sagas, myths and legends.
For example, it is said that a forgery workshop was operated here during the 30-year war. Popular scientific theories go back even further, according to which the cave was the historical scene of events that can be found in the dramatic descriptions of the Middle High German Nibelungenlied. At the beginning of the 19th century, the large cave room was used as a workshop by a saddler and strap cutter.
