도르테아 광산은 1988년에 탐사 갱도로 개설되었습니다. 주로 중정석을 찾기 위한 것이었습니다. 그러나 철광석과 망간광석이 너무 많이 섞여 있어 경제적으로 채굴할 수 없습니다. 갱도를 개설하면서 1536년에 이미 언급된 오래된 도르테아 광산의 잔해도 발견되었습니다. 탐사 갱도의 운영은 1992년에 이미 중단되었습니다. 2007년부터 2009년까지 새로운 조사가 이루어졌으나, 그 작업은 현재 완전히 중단되었습니다.

Unter Sophia 광산은 오늘날 막혀 있지 않은 Forbachtal의 몇 안 되는 광산 중 하나입니다. 북부 슈바르츠발트에서 유일하게 코발트가 채굴되었습니다. 이 광산은 1593년에 처음 언급되었으며, 1757년까지 운영되었을 것으로 추정되며, 그 후 폐쇄되고 매립되었습니다. 1995년경에야 광산 입구가 다시 발견되었습니다. 요청 시 가이드 투어가 가능합니다. https://www.nationalparkregion-schwarzwald.de/poi/baiersbronn-friedrichstal-grube-sophia

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.
