B8 BERGKRISTALL - ESCHE II
Underground Plant
With more than 50.000 m2 (some 10 km tunnnel length) one of the biggest german underground installations that reached production status in late 1944. According to Allied intelligence reports, it was "one of the most modern and most complete underground plants in Germany".
Constructed within 13 months by prisoners of the KL Gusen II concentration camp within the Mauthausen-Gusen complex due to its high mortality (up to 98%), it became one of the most horrible concentration camp sites in European history (average survival period 4 months).

Production started in parallel to construction of the tunnel-system in Summer 1944 and reached maximum in April 1945 (some 90 jet-plane fuselages, fully equipped per
