Roman mining of iron ores
In the southern Markgräflerland between Schliengen, Liel and Hertingen there are deposits of bean ore which have been exploited and smelt since the 19th century. Bean ores are iron ores no bigger than a fist, extracted in open-cast mines and in small galleries. In Hertingen, during the excavation of a Roman estate, remains of a smelting furnace for bean ores were discovered. It is assumed that iron smelting was the main source of income for the people living on this Roman estate. In the forest in the East of Hertingen deep craters and slag heaps are visible. These are still witnesses to the former bean ore mining.
