The castle is built on a rare basalt rock formation, which is a volcanic plug that escaped erosion.
It was constructed around 1146 under the direction of Bishop Otto of Bamberg.
The site includes a chapel dedicated to St. Stephen, which dates back to the 13th century.
Evidence from excavations confirms that the Griffen hill was inhabited as early as 4000 BC.
The fortress was strategically designed to secure the transit route between the Bamberg possessions in Carinthia.
It survived several military conflicts before falling into ruin following a fire in the 19th century.
Burgruine Griffen is a 12th-century hilltop castle ruin situated atop a 120-meter high volcanic basalt cone in Carinthia, Austria. Founded by the Bishopric of Bamberg, the fortress served as a strategic administrative and defense center throughout the Middle Ages. The site features the remains of the main tower, curtain walls, and a small chapel. Visitors access the ruins via a steep, winding trail that starts from the base of the Schlossberg. The structure offers an elevated vantage point over the Jaun Valley and the surrounding Lavanttal Alps. In 2026, the site remains preserved as an open-air historical attraction managed by the municipality of Griffen. Archaeological excavations on the hill have revealed traces of settlement dating back to the Neolithic period.

Wear sturdy, closed-toe hiking shoes as the access path consists of loose gravel and steep, uneven terrain.
Carry water, as there are no refreshment stalls or vending machines located within the ruin walls.
Visit during the shoulder seasons to avoid the heat trapped by the basalt rock during summer afternoons.
Do not attempt the climb in flip-flops or open sandals, as the incline is physically demanding and slippery.
The path is generally accessible year-round, but can be closed during extreme winter icing or heavy storm conditions.
Maintain caution near the historic masonry walls, as some sections are unroped and unstable.
