Another boom began in the early 18th century after the loss of the Alsace to France. It lasted until the 19th century. Many pits from this period may be visited today as show mines; for example the Teufelsgrund Pit (Münstertal), the Finstergrund Pit near Wieden, the Hoffnungsstollen (Hope Gallery) at Todtmoos, the mine in the Schauinsland, the formerly especially silver-rich Wenzel Pit in Oberwolfach and Gr. Segen Gottes (God's Great Blessing) in Haslach-Schnellingen.
