Secret Nazi weapons facility discovered near concentration camp

The claim is that an underground research facility has been located near the Austrian town of St. Georgen an der Gusen, site of the Mathausen-Gusen concentration camp. Further, the claim is made that a big concrete slab is a cover to a V-2 launch silo.

Well… maybe.

The Austrian government has shut down the dig for bureaucratic reasons. Insert Conspiracy Theory HERE.
