The mysteriously illuminated gallery has some special treasures to reveal. Watch the children's eyes sparkle like the jewels themselves as they enter this secret underground world.

No matter whether you choose to make a tour with a competent guide or if you prefer an expedition into the core of the mountain: the gallery will reveal some of its secrets and we have done our best to prepare these treasures for you. A small underground lake, a mystical starry sky and garnet veins of geological interest that run through the entire gallery are put in perspective.

The gallery is also used for special events in impressive surroundings – concert, theatre or even weddings. By the way: The tunnel has a constant temperature of 8 degrees Celsius – don’t forget your jacket!
