Oswaldhöhle
Oswaldhöhle is a natural karst cave located on Hollow Mountain (also known as High Cross). It is a passage cave that is roughly 65 m long. The cave served as a shelter and later as a rock cellar in history. The largest room of the cave, the "Great Hall", is about 40 meters long and is divided by two rock pillars. As a bonus there are often beautiful ice formations in winter.
