Teufelstein, Mountain summit in Styria, Austria.

Teufelstein is a summit in the Fischbach Alps that reaches approximately 1,500 meters in elevation. Its distinctive feature is a natural formation of three stacked rock blocks standing about 20 feet (6 meters) high.

The mountain's name comes from medieval folklore about the Devil attempting to build a tower to heaven by Christmas Eve. This legend shaped how local communities understood and spoke about the place for generations.

The name Teufelstein comes from a legend in which the fallen angel Lucifer tried to build a tower reaching heaven here. The rock itself is a cult site wrapped in legend, and the three stacked blocks near the summit are the goal of walkers on the marked trails.

The hike to the summit follows a circular route of about 9 kilometers with roughly 450 meters of elevation gain. Starting points are located near Zellerkreuz and the Fischbach parish church, both offering clear access and trail markers.

The summit rock consists of three stacked blocks about 6 metres high. Geologically it results from weathering, where harder rock outlasts its surroundings; such formations are called "Ofen" in the eastern Alps. Legend says the fallen angel Lucifer tried to build a tower here reaching heaven.
