Petershöhle, Donautal, Medieval cave castle in Beuron, Germany
The Petershöhle is a cave castle with natural chambers embedded in limestone rock within the Danube Valley. The main room opens toward the south with views of the river landscape, while a smaller side chamber extends back into the rock.
The cave was inhabited in the 12th century by regional nobility and likely served as shelter or dwelling space. Excavations have uncovered pottery and ceramic hearth pieces from that era, indicating regular occupation.
The name references Saint Peter, reflecting the spiritual connection to the nearby Benedictine abbey. Visitors can still see how this relationship shaped the cave's location and orientation.
Access is via a steep wooden walkway with about 50 steps leading directly to the entrance. Sturdy footwear and caution are needed, as the path is steep and can be slippery when wet.
The rear section of the cave contains a natural shaft that allows light to reach the inner areas, making the space surprisingly bright. This light shaft was a practical solution for the former inhabitants to provide ventilation and illumination.
