An underground weapons bunker built by Nazis to test nuclear and chemical weapons has been unearthed in Austria.

It was built using slave labor from the nearby Mauthausen-Gusen concentration camp. Austrian documentary filmmaker Andreas Sulzer noticed a reference to the subterranean site in the diary of an Austrian physicist recruited by the Nazis. The stronghold was located near the town of Sankt Georgen an der Gusen, and not far from the Bergkristall factory where the first operational jet-powered fighter, the Messerschmitt Me 262, was invented. Footage from the previously-unearthed Bergkristall site is below.

From The Independent:

Its exact location was determined using intelligence reports and radiation tests, which revealed higher than normal levels of radioactivity.

Andreas Sulzer, the filmmaker who is leading the exploration, discovered a critical 1944 report by the forerunner to the CIA, from an American spy who noted the existence of a secret weapons programme in the area.

Sulzer told the Sunday Times, “Prisoners from concentration camps across Europe were handpicked for their special skills--physicists, chemists or other experts--to work on this monstrous project and we owe it to the victims to finally open the site and reveal the truth.”

From the International Business Times:

It is believed that an estimated 320,000 inmates died building the labyrinth of concrete tunnels and shafts.

It is believed to be the location of a secret weapons programme, led by SS General Hans Kammler. Kammler is thought to have lived on the site during the war. Rumours continue to surround his death, with some suggesting he was given a new identity by the US government in exchange for details on Nazi weapons research.

The deadly V-2 rocket which struck at London during the final months of the World War II was tested at the complex. It is also thought that scientists experimented with the use of radioactive material and chemical gas.

    The video is part of the fimmaker's older research. It shows part of the already documented part of the bunker/former factory that is considered relatively well explored.

    However the independent researcher had argued there was more to the site than the few areas already uncovered, and after getting permission from the private landowner did some more drillings of his own and actually found previously undiscovered system of tunnels. He managed to retrieve some SS helmets and other Nazi stuff.

    A professional and specialised research institute for former war sites will take over the excavation in the near future.

  2. Did the headline read Australia before???? If not, my eyes hosed me again. Austria makes a lot more sense. Australia woulda made a better story.

  3. There was a collosal explosion in WA back in the 90s, just south of a sheep station owned by the Aum Shinrikyo cult.

    There's a persistent myth that it was caused by a small nuclear device.

  4. On a gut level, that number seemed a bit outlandish. If construction took one year, that's 900+ people a day dying to build this. Of all of the atrocities committed during this era, this alone would be one of the worst and most efficient means of killing.

  5. Why, those Nazis were as bad as Nazis!
