Tunnel Facilities

The tunnel facilities are an integral part of the camp grounds. After the Soviet military authorities had the entrances blasted in 1947/48, the underground facilities were sealed for several decades. The tunnel system has been accessible once again since 1995 through a newly driven tunnel. As few changes as possible have been made to the state of the tunnels as found at that time. Destroyed factory installations, production remnants and fallen rocks cover the floors of the former assembly chambers in wild disarray. Parts of the tunnel facilities have been flooded by groundwater.


Tunnel A

A small section of the tunnel facilities is accessible within the framework of guided tours starting at the museum. This section includes part of one of the longitudinal tunnels (“Tunnel A”) and three transverse chambers which served as inmates’ living quarters until June 1944.


Model of the underground facilities in Tunnel A

In the entrance area of Tunnel A, wall plaques provide information on the inmates’ living and working conditions in the underground facilities. A model gives an impression of the facilities’ overall dimensions.


Transverse Tunnels

From the autumn of 1943 to June 1944, four transverse tunnels served as concentration camp living quarters. The hygiene conditions in these “sleeping tunnels” – which were furnished with four-tiered wooden bunks – were disastrous. After June 1944, these transverse tunnels were used for the assembly of the V1 flying bomb by inmates. The V1 scrap scattered on the floors testify to that phase.
