Top 10 Caves フロイデンシュタットでの

Mühringenの上にある急な登り坂では、アイアッハ渓谷の風景が本来の自然のままの姿を見せてくれます。森に覆われた斜面にある小さな洞窟の入り口が、特別な見どころとなっています。道は急な上り坂で、谷の美しい景色が繰り返し開けてきます。

ドロテア鉱山は、1988年に調査坑道として建設されました。ここでは主に重晶石を見つけることが目的でした。しかし、鉄鉱石やマンガン鉱石が多すぎると経済的に採掘できないことが判明しました。 坑道建設中、1536年にすでに言及されていた古いドロテア鉱山の遺構も見つかりました。 調査坑道の操業は1992年にすでに中止されました。2007年から2009年にかけて新たな調査が行われましたが、その作業も現在では完全に中止されています。

ゾフィア・ウンテレ鉱山は、フォルバッハタール渓谷にある数少ない、今日でも坑口が埋められていない鉱山の一つです。 そこではコバルトが採掘されていました。これは北黒森地方では唯一の例でした。この鉱山は1593年に初めて言及され、おそらく1757年まで操業されていましたが、その後閉鎖され埋められました。1995年頃になって初めて、鉱山への入り口が再発見されました。 ガイド付きツアーはリクエストに応じて可能です。 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.
