Caves and mines
Caves, grottoes and abandoned mine shafts in Thuringia entice visitors into an unknown fairytale world. The Saalfeld Fairy Grottoes belong to the most famous ones. They are even listed in the Guinness Book of records as "the most colourful grottoes in the world". The Sondershausen Adventure Mine is also used for festive and sporting functions and the mythical Barbarossa's Cave is a source of excitement and delight. The Marienglashöhle Visitor Mines near Friedrichroda belong to the largest crystallised gypsum grottoes in Europe. Former mines like the Rabensteiner Stollen Mine in the Southern Harz take the visitors on a trip into the past of mining.
