During the period of coal shortage after World War II, the remains of existing coal deposits were extracted from this tunnel. The mining operation was probably not registered, so the name of the tunnel cannot be determined exactly. The Aufgottgewagt mine, which was last granted mining rights here in 1774, had left the coal remains standing in earlier times. In front of the tunnel entrance there was a loading ramp from which the coal was loaded for further transport. Source: Panel 30 at the tunnel entrance (route•industriekultur•)
