A very special treasure are our magnificent crystals. They bear witness to the beauty of inanimate nature. We present mining specialities from the province of Salzburg (salt, gold, arsenic, tungsten) as well as world famous mineral forms especially from the Hohe Tauern mountain range. The main attraction are our world famous giant rock crystals (maximum 618 kg). A whole room is dedicated to the geological diversity of our province, illustrated by mineralogical and palaeontological showpieces. Beautiful minerals from all over the world complete the collection. In out "treasure chamber" we present one of Europe's most beautiful collections of gemstone and gold samples.
