On September 21st 2005 the crystal hunters Franz von Arx and Paul von Känel opened up a cavity in the rock of their exploratory mine on the Planggenstock peak in the canton of Uri. There, glinting in the light of their torches, were almost fifty large, unusually clear and perfectly formed quartz crystals and crystal clusters. The two were looking at one of the largest and most important finds which the alps had yielded for around 300 years.

In the exposition you're finding a booklet in english.
