 Already by the 18th century, the Potzberg mines were offering the populace jobs, as too were the quarries on the Remigiusberg's eastern slope by the 19th century.In 1862, the government in Speyer gave its approval for the opening of a quarry, which began work forthwith, although in the beginning it was not run very efficiently.In 1877, a few quarrymen opened another quarry under their own management, which did better for a time, until the Second World War broke out.
