Austrian filmmaker Andreas Sulzer claims to have found Hitler’s ‘largest secret weapons research facility following information contained in US intelligence reports describing a massive underground tunnel system excavated in granite near the Mathausen-Gusen concentration camp.
Sulzer has been trying to uncover this Nazi secret weapons nest for years. Using data gathered from countless documents found in German, Russian, and American archives — from aerial photographs to interrogation records — he believes that there’s no doubt that this underground complex exists. He also claims that he has evidence of the secret facility’s purpose, which he found in the letters of an Austrian physicist who wrote about how they were trying to “smash atoms” in secret bunkers near St. Georgen an der Gusen, the little Austrian town by the Mathausen-Gusen camp.
The entrance to the tunnels leading to the facility were destroyed by the Allies right after World War II. Now, Sulzer and his team have been excavating in the area and claim to have found definitive physical evidence of the secret installations.
According to Austrian newspaper Kleine Zeitung, the archeological works have been halted after Sulzer and his crew removed a six-foot-deep clay layer that covered a massive granite entrance with concrete steps. Sulzer has also uncovered a huge octagonal concrete slab, which he had previously identified in reconnaissance photographs of the area taken by the Allies. Aerial photos from May 8, 1945, no longer show the concrete shape but the patch of farm land that his team has now removed.
Talking to Austrian newspaper Der Standard, Sulzer says that analysis of the terrain indicates that the concrete slab is covering a large cavity. He thinks that this cover was used to cover a silo for testing of V-2 rockets, much like the covers used in US and Soviet missile silos.
The theory of the launch silo makes sense, as the facility may be connected with tunnels to another known underground site near this one, the B8 Bergkristall — a 50,000-square-meter (540,000-square-feet) factory built and manned by prisoners of the Gusen II camp in 1944. This installation was used by the Germans to make the Messerschmitt Me 262 jet fighter (they were able to produce 1,250 planes per month) as well as V-2 rockets. Having a launch test site near B8 Bergkristall is logical.
Sulzer believes that the Nazis were using the secret underground site near B8 Bergkristall to research bacteriological, chemical, and radioactive warheads to equip V-2 rockets.

Aside from these constructions, Sulzer has found several Nazi objects on the site, including this Waffen SS helmet
It seems that there may be something hiding behind these buried structures, but we will have to wait to see if it’s really the largest secret weapons research center of the Third Reich. For now, the Austrian authorities have halted Sulzer’s works and put the site under their protection, claiming that he doesn’t have the permits to conduct this dig.
