Limestone, which is characterized by its great hardness, was first quarried here in the Drewer quarry 140 years ago for road construction.
After cleaning and clearing, the quarry was placed under nature protection in 1997 and closed off with a massive gate. This measure serves to preserve communities or biotopes of certain wild animal and plant species, in particular rock-breeding bird species, bats and amphibians as well as plant and animal communities of semi-arid grassland. Today, the Drewer quarry is a vivid example of the renaturation of a former quarry through natural succession. Nature has reclaimed the site.
