In 1168 the castle Freudenstein was constructed to protect the silver mining. In 1500 „Heinrich der Fromme“ lived there. During the following centuries the castle was used as a military base, a military hospital and a grain silo. Between 2005 and 2008 it was restored fundamentally. Today it houses the world’s greatest collection of minerals, the archives of the city Freiberg and a restaurant.
Different cylinders types of ABUS are used to secure the historical building.
