The museum (open June – October) shows how for 300 years the mountain people on the Mot Madlain dug out the ore by hand before smelting it in the valley (Schmelzra) in order to obtain the precious silver and lead. From the tools and carts of that time shown here, you can see vividly how the miners and the farmers lived. There is also a permanent special exhibition about the last bears hunted in Switzerland.
