The old Romans have sanded Buntsandstein here for their houses, water systems or funerary monuments. The Schlegelspuren on the stone stairs suggest that the quarry in the 2nd / 3rd Belonged to a private entrepreneur, who occasionally had stones demolished here.

The colored sandstone of the Northern Eifel was used in Roman times for building houses and water pipes as well as for the erection of grave monuments and consecrated stones.
Along the stepped rock face near Kall, clear signs of degradation can be seen over a width of about 11 m. Roman quarry workers hewed long rectangular cuboids of approx. 30 cm in thickness out of the rock (“scraped free”). The crest-like slash marks arranged in an arc testify to Roman mining techniques. With iron picks (bicorn), the workers first chopped the corridors around the individual blocks and dug them into the rock to the desired thickness of the cuboids. At the front they then made wedge holes in the rock, into which they then drove iron wedges with a sledgehammer. The blocks detached from the solid surface by striking the wedges.
The relatively small size of the Kall quarry suggests that blocks were only occasionally broken for local use. While quarries on the Rhine and in the North Eifel were otherwise mostly imperial property and were operated by the military, the sandstone quarrying here, similar to that at the cat stones near Mechernich, was probably carried out by a private entrepreneur.
