The Kraushöhle was named after its explorer and developer Regierungsrat Franz Kraus. He was the father of speleology in Austria. The forecourt of the cave includes a monument to him.
A winding tunnel leads down to a huge main chamber called The Ballroom, with several small and short side passages. It is a karst cave with some dripstones, but it is famous for its gypsum (CaSO4) speleothems. A nearby sulfuric spring, which was used for bathing at the beginning of the century, is a logic explanation how they were formed. Warm sulfuric water from the same source once filled the cave. The soluted limestone and the sulfur in the water caused a chemical reaction which produced the gypsum. Latest scientific research in Lechuguilla and other caves make it very likely, that sulfur loving bacteria produced the gypsum by feeding on the sulfur.
This cave is unique in Europe: it is one of only two limestone cave with this kind of sulfuric speleothems, which is also a show cave. The other one is Grotta Grande del Vento, Genga, Italy. Similar caves can be found all over the world, and the most famous is Lechuguilla Cave.
And another strange thing: this is the very first cave in the world with electric light but today it is one of the last guided with carbide lamps. The electric light was installed by Franz Kraus in 1883 and it was powered by a water driven generator, which was built at the brook below. But this early electric light did not work very well. After seven years it had to be shut down, because of technical difficulties and too high costs. The installations were removed completely and today this cave is one of the last show caves in Austria still visited with carbide lamps.
