Hoffnungsstollen Mine is located in the Black Forest, in the village of Todtmoss only 30 kilometers north of Waldshut-Tiengen. Magnetkieserz were mined for a few years by the owners who claimed the mining rights in 1798 in the Todtmoos orers as well. After a few years of mining, when nickel was discovered, underground mining became unprofitable due to technical difficulties and the falling prices of the nickel.
It was abandoned in 1937 and opened to the public in the year 2,000.
