Hiking around Sundern
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

The Balver Cave is the largest open cultural cave in Europe with an entrance portal that is 11 meters high and 18 meters wide. In the huge hall, which is almost 90 meters deep and splits into two arms after 54 meters, around 2,000 people can celebrate or experience the unique acoustics and atmosphere at concerts. Caves only exist in limestone. This grew from dead corals in a warm sea around 360 million years ago. The enormous forces of the earth's interior fold, raise and lower the originally crack-free mass limestone. Penetrating water dissolves the lime, widens the cracks into crevices and cavities - this is how our cave was formed over tens of millions of years. During the ice ages 100,000 to 20,000 years ago, mud was deposited in the Balver Cave. The cave clay filled the cave almost to the ceiling. The farmers recognized the high fertilizer value of the phosphate-containing clay and brought it to their fields. This is how the impressive cave space was uncovered - a rock dome. During later excavations, skeletons of local animals, such as mammoths and cave bears, and around 40,000 artifacts were found.
