The Balver Kulturhöhle impresses right from the first step: a gigantic natural dome, up to eleven meters high, which has been used since the Old Stone Age and is today considered an extraordinary event venue. Where Neanderthals and cave bears once found shelter, you can now experience concerts, theater, and the traditional Schützenfest (marksmen's festival) in an acoustics that is second to none. The cave is only accessible as part of events or guided tours, but a glance at the mighty entrance is enough to reveal why it fascinates as Europe's largest open hall cave. https://www.sauerland.com/de/neusta-pois/balver-hoehle-europas-groesste-kulturhoehle

Large cultural cave with a restaurant right next door. The cave is said to have great acoustics. Unfortunately it was closed when we were there.

<< The cave in Herpel >> "...The mine tunnel was first mentioned in 1912. At that time, farmer Josef Stahlhacke was looking for clay for his farmhouse and came across the cave. There were also stories that the farmers from Schreibershofer Grund suspected a copper ore vein. The rich ore vein never materialized. The hammer and tunnel became the property of the coppersmith Georg Scheiteler, who went bankrupt and committed suicide. During the Second World War, the cave served as an air raid shelter. Some of the older Herpel residents can still remember how they sought shelter from bomb attacks with their parents and siblings in their childhood. 52 years after the end of the war, on June 29, 1997, the buried mine tunnel was reopened. Today it is 22 meters long and has a width of 0.8 to 1.2 meters, and a height of 1.6 to 2 meters. A An attractive hiking rest area has been created, which is used eagerly by the people of Herpel..." https://www.lokalplus.nrw/drolshagen/die-hoehle-in-herpel-ist-ein-lieblingsplatz-der-dorfbewohner-74617

A mine artificially created by mining, at first glance it looks like a limestone cave, at least the entrance.

A nice walking area. Since I don't take a photo of every bench or similar "highlights", I am attaching a photo collage of photos from the region.
