In the sandstone boulders of the east, there is a row of these mostly naturally occuring rock shelters, modified by humans. Excavations have revealed that many of these notable shelters, such as this one, were used by Stone Age people in the Mesiolithic period (approx. 8000–6000 BCE) as the ice retreated northward after the last ice age. This ideal shelter here, in the roof of which even the untrained eye can find traces of human activity, offers an unimpeded view of the low-lying terraine. In the rear, it is protected by the solid rock wall, it was easy to defend.
