Summit of Külpmann Quarry

Until a few years ago, Ruhr sandstone was mined in the Böllberg quarry to produce floor panels or facade panels, for example. The old factory building originally belonged to the Neuwuelflingsburg colliery, which worked here until 1967. In the walls of the quarry, primeval tree trunk remains up to 2m long were occasionally recovered during mining. They are remnants of a former forest bog landscape that existed during the Upper Carboniferous (320 to 296 million years before today).

The Külpmann quarry is located on the Böllberg in Albringhausen, Wetter (Ruhr). Ruhr sandstone was mined in the quarry. The site was operated by the Külpmann family from 1932. The company filed for bankruptcy in 2012. Since 2013 there has been a sales warehouse for a natural stone dealer here. The quarry wall is a geological outcrop from the Carboniferous period that still exists today.
