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.

The Barbarossa Cave was discovered purely by chance. The idea was to revive copper shale mining in the Kyffhäuser region. In 1860, the entrepreneur Wilhelm von Born therefore had a tunnel dug beneath the ruins of the Falkenburg and directly on the old salt road to Bad Frankenhausen. Meter by meter, the miners penetrated further and further into the mountain. And then: after a distance of 178 meters, on December 22, 1865, the mountain suddenly opened up in front of them - they came across natural cavities of impressive size and beauty.

The South Harz gypsum karst landscape stretches for around 100 kilometers in length but only a few kilometers in width on the southern slope of the Harz Mountains. Here you can find a wide variety of karst phenomena such as sinkholes, dolines, caves and stream sinkholes, which are unique in Europe in such large numbers in such a small area. The gypsum karst area in the South Harz is the largest and most important gypsum karst area in Central Europe. The Gipskuppe is one of the unique areas worth protecting.

The Gründelsloch near Kindelbrück is one of the most impressive and important karst springs in Thuringia. It was created by the dissolution of limestone in the subsoil. The resulting underground cavity collapsed in 1611, causing a sinkhole and the spring to emerge. The active karst spring, with a diameter of 22 m and a discharge of around 15,600 l per minute, has several older precursor springs that are lined up like a string of pearls from northwest to southeast in the area of the Kindelbrück fault zone and dried up again over time. Examples of these dried-up precursor springs are the Kuhborn, around 700 meters away, or the karst spring on the Steinrinne. Source: display board
