The Barbarossa Cave covers 13,000 square meters and is one of only two existing show caves in the world, made of anhydrite rock, making it a geological rarity. The unique charm of this magical subterranean world lies in the uniquely beautiful, multi-layered play of colors of the white to gray rock.

For me one of the most beautiful stamp points of the Harz hiking badge.

The Reesberg doline lies on a geological boundary between the Bunter sandstone and the anhydrites of the Zechstein. The spring water emerging from the Bunter sandstone is very clear and therefore has a high dissolving potential. It can absorb up to two grams of gypsum per liter and then flows underground.

The Barbarossa Cave was discovered purely by chance in December 1865 by miners searching for copper slate and was opened to the public as a show cave just two weeks later. On the approximately 800 m long, exciting journey of discovery through Barbarossa's underground kingdom full of wonders and secrets, you will experience earth's history with all your senses and at the same time learn a lot of interesting things about Emperor Friedrich I Barbarossa and the old legend that surrounds him. Be enchanted by huge, expansive cavities and crystal-clear, shimmering blue-green lakes with their breathtaking ceiling reflections. Spectacular and unique in the world: In the “tannery”, bizarrely curved “plaster rags” over a meter long hang down from the ceiling, reminiscent of hides and hides hung up to dry. The cave rock anhydrite (CaSO4) absorbs the high humidity like a sponge and thereby transforms itself into gypsum.

The region around Heringen/Helme is known for its distinctive karst geology. You'll find unique formations such as sinkholes, like the Reesberg Sinkhole, and fascinating cave systems, including the rare Barbarossa Cave. The landscape is shaped by soluble rocks like gypsum and anhydrite, leading to phenomena such as episodic lakes like the Farmer's ditch.
The Barbarossa Cave is one of only two accessible anhydrite caves in the world and the sole anhydrite show cave in Europe. Its unique charm comes from the beautiful, multi-layered play of colors in its white to gray rock, and it features huge cavities and crystal-clear, shimmering blue-green lakes. A particularly unique feature is the 'tannery,' where bizarrely curved, meter-long 'plaster rags' hang from the ceiling.
The Reesberg Sinkhole is an impressive natural monument formed by a geological process where spring water emerges from beneath a Bundstein sand layer. This water dissolves gypsum and carries it away, creating the sinkhole over time. Surface water then disappears into the sinkhole, continuing its flow underground within the anhydrite rock.
The Farmer's ditch is a captivating episodic lake, meaning it fills with water irregularly. It's a significant natural phenomenon along the Karst Trail, showcasing the dynamic nature of the region's karst landscape. Visitors find it impressive whether it is filled with water or dry, revealing the meanders of the Glasebach stream.
