Feggendorfer Stollen, Coal show mine in Lauenau, Germany

Feggendorfer Stollen is a coal mine in Lauenau with underground passages and chambers created over nearly two centuries of extraction work. The site contains original tunnel systems and work areas where visitors can observe the physical layout and methods used to remove coal from the rock.

Coal extraction at this site started in 1831 and supplied nearby brick factories, lime kilns, and metalworking shops with fuel for their operations. The mine closed in 1952 when demand for local coal declined.

The mine's name comes from the hamlet of Feggendorf, and its mouth sits 255 m above sea level in a hollow between two spring valleys of the Schlierbach. Since 2017 it has been one of three recognised teaching mines in Germany, where trainees and mining students work shifts to learn the craft "from the pick upwards". A miners' festival in September 2013 opened the rebuilt Zechenhaus.

Arrange visits in advance to ensure a guide is available and learn about safety requirements for exploring underground areas. Wear warm, practical clothing suitable for cooler underground conditions.

Since spring 2017 the Feggendorfer Stolln has been recognised as one of Germany's three official teaching mines. A demonstration coal face was set up so that apprentices and mining students can work shifts there and learn the craft from the pick upwards.
