The Dorothea mine was created as an exploration tunnel in 1988. The primary target here was to find barite. However, this mineral is not economically viable because it is too heavily interspersed with iron and manganese ores. During the construction of the tunnel, remnants of the old Dorothea mine, first mentioned in 1536, were also discovered. Operation of the exploration tunnel was discontinued in 1992. Further explorations were conducted between 2007 and 2009, but these activities have since ceased completely.

The Untere Sophia mine is one of the few in the Forbach Valley whose entrance is not filled in today. Cobalt was mined there – a unique occurrence in the Northern Black Forest. The mine was first mentioned in 1593; it was probably in operation until 1757, after which it was closed and filled in. The entrance to the mine was only rediscovered around 1995.

A very informative information panel on the geology and history of mining in the Forbach Valley. If you look into the tunnel entrance, you can see the remains of a barite vein on the ceiling. Barite (heavy spar) was the accompanying material around which iron, silver, and copper ore had been deposited. Just a few meters from the tunnel, the Sachtleben company had core drilling carried out in 2017 to explore the thickness and purity of the barite vein, with the aim of possibly reviving mining. However, the results of the core drilling were sobering.

In the 18th century, mining played an important role in the Alpirsbach monastery. In the area of today's Alpirsbach town center, the Wolfgang and Eberhard mines brought in the most revenue. Two parallel barite veins contained rich cobalt ores in some places. The ore veins were opened up by extensive mine works, which, with the exception of the surface shafts, have been preserved to this day. Mining and blue dye production contributed significantly to Alpirsbach's economic boom at that time. Source: Display board

The "Untere Sophia" mine is one of the oldest mines in the area. It is already marked on a map by Georg Gadner from 1593. At that time, however, the tunnel was still called "St. Johannis am Friesenberg."

Nature - historical hiking trail Eutinger Tal 3. Former beer cellar of the Sonnenwirt At the entrance to the Eutinger Tal, at least five beer cellars were carved into the shell limestone, in which the innkeepers kept their freshly brewed beer at a constant temperature. At the end of the cellars, a chimney-like shaft provided ventilation. Bat cellar Abandoned beer cellars are winter quarters for various bats (e.g. the local barbastelle bat) and amphibians (e.g. fire salamander), which depend on a frost-free and undisturbed retreat.
