The small and sleepy town of St. Georgen an der Gusen in Austria holds some very dark secrets.
During WWII it was home to the Nazi Mathausen-Gusen Concentration Camp where thousands upon thousands of Jews were systematically murdered.
Nazi death camp survivors cheer on Allied soldiers as the concentration camp of Mathausen-Gusen is liberated. Thousands of prisoners at this camp were used to construct underground catacombs that made up the B8 Bergkristall weapons facility in St Georgen an der Gusen, and possibly an additional facility that was used for research on nuclear fusion, a.k.a. creating an atomic bomb!
