Granatium Radenthein

The Granatium in Radenthein, Carinthia, is an experience-museum dedicated to the garnet — built on Europe's only walkable garnet vein. Visitors explore the Granatmuseum, the Granatzimmer (a room built from 80 tonnes of garnet stones), the Karfunkelstollen mine tunnel, and an outdoor prospecting field where they can search for and keep their own garnet.
