Riegersburg Castle

Riegersburg Castle is a medieval castle situated on a dormant volcano above the town of Riegersburg in the Austrian state of Styria. The castle is owned by the Princely Family of Liechtenstein and contains a museum with changing exhibitions. Riegersburg Castle is situated at an height of 450 m.LocationThe castle was built on a hill which had once been an ancient volcano. To be precise, it is the petrified remains of the solidified molten interior, a volcanic neck of a large stratovolcano that probably became extinct two or so million years ago, like other similar hills in north-central Europe. The peak is at 482 meters above sea level. The ancient basalt of the hill was used to build the castle.
