A large staircase for pedestrian traffic was near the highest point of the cavern, which led to an exit.

Beside the stairs were rails that assisted in transport of earth from the cavern as it was being enlarged for German forces.

The angle of this stair and matching rail system was estimated to be 30 degrees, and the height of the chamber approximately 175 feet.

After the end of World War II, the cavern was occupied by the U.S. Army, in the late 1980s by a communications company.

Other small Army posts within this group were located at Munchweiler, Fischbach, and Clausen.
