 Both Theisberg and Stegen were originally farming villages, but in the latter half of the 19th century, the number of working families was already growing quickly with the opening of the quarries on the Remigiusberg.Working families moved to the village, which explains why the population rose so quickly, and also partly why the Catholic share of the population also swelled, from its original 20% to 40% in the mid 20th century.Even before this, Stegen had grown in the 18th century to be the bigger of the two villages.
