Bensenbruch at the end of the Second World War. Since Gailbach and Dörrmorsbach became a combat zone during Holy Week 1945, people took refuge in cellars and tunnels to avoid bombs and grenades. People also sought refuge in the Bensenbruch, an old quarry. An approximately 15 meter long and over 2 meter high room in the form of a cellar vault could accommodate 50 to 60 people.

Bensenbruch Two caves remain from the former Bensenbruch. In the larger one, 50 to 60 people could find shelter during a bomb attack in 1945. The lamprophyre dike is bordered by the basal breccia (Buntsandstein) alternating with siltstones from the crumbly slate series.

The Antonius Grotto is a very well-maintained facility. It's a place created out of gratitude. Here you can also take a break in the refuge.

The Teschenhöhle is the remains of a quarry from which basalt was mined. This basalt formed a volcanic vent that formed about 43 million years ago. During the eruption, the layer of red sandstone that had not yet been removed here was broken through. You can observe this in the rock, which consists of a volcanic breccia with parts of red sandstone that was deformed by the violent eruption

The Teschen Cave is not a cave in the true sense, but a large hole that goes back to a quarry. So don't expect too much there! In no case (in search of the "cave") try left or straight ahead to climb up the mountain. This is extremely dangerous because slippery!
