Frölich Tunnel Sosa

The history of the Frölich-Stolln goes back to 1870, and the first ores were brought to light seven years later. Bismuth and cobalt ores were mainly mined. However, in 1883 the shaft was closed again because the mining rights were declared to have expired. The facility is currently being maintained, so it will be possible to visit it again in the near future - but primarily on special occasions.

The Frölich-Stolln is one of the youngest mines in Sosa and belonged to the mining area of the "Sosaer Glück" mine.
On December 12, 1870, the owners of the "Sosaer Glück" mine and the owner of the property, Hermann Frölich (owner of the Frölich estate in Sosa) signed a binding contract "For the sinking of a digging shaft...". In 1872, mining activities began in the Frölichwald. Ore extraction was recorded from 1877 onwards. Around 64 hundredweight of bismuth and cobalt ore were extracted in total before the Frölich-Stolln was closed. On October 3, 1883, the mining rights of the "Sosaer Glück" mine were declared extinct. At this point at the latest, mining work also ended in the Frölich-Stolln. After the Second World War, the tunnel was examined again by SDAG Wismut, but no ores worth mining were found. During the construction of the dam (1949-1952), the two terraces were created and the so-called "culture barracks" for the dam builders stood on the terrace above. After that, the area was used as a summer camp for children's and youth holiday camps. The lower terrace is now leased by the Sosa mining brotherhood. The members reopened the Frölichstolln in 1996 and made about 70 m of it accessible. In the future, it will be possible to visit the facility again on special occasions - such as the annual midnight mass.
