It is the highest altitude castle ruin in the entire province of Styria.
The name Steinschloß refers to its position on a rocky outcropping, which served as a natural defensive foundation.
The structure historically controlled vital mountain passes used for regional salt and iron transport.
Unlike many Austrian castles converted into palaces, Steinschloß was largely abandoned and left to decay after losing its military utility in the late Middle Ages.
Burgruine Steinschloß is the highest-lying castle ruin in Styria, situated at an elevation of 1,180 meters above sea level. Originally constructed in the 12th century, the fortification served as a strategic watchpoint guarding the route between the Mur and Friesach valleys. The site consists of substantial remaining masonry, including parts of the residential tower and defensive curtain walls. Archaeological excavations have recovered medieval pottery and iron implements now associated with the castle's domestic life. Visitors can access the ruins via a steep hiking trail starting from the valley floor. The site remains largely unmaintained to preserve its character as a rugged, authentic ruin rather than a reconstructed monument.
