WATCH: Creepy Underground Nazi ‘Terror Weapons’ Bunker Uncovered

A newly uncovered underground nazi complex has been discovered near the town of St. Georgen an der Gusen, Austria. Experts believe the bunker was built just before the end of World War II and was probably used to create weapons of mass destruction.

According to Austrian filmmaker Andreas Sulzer, the site was constructed with slave labor from the Mauthausen-Gusen concentration camp.

Excavations on the site revealed that there were high levels of radiation, which points to the probability that the Nazis were working to develop nuclear weapons.

The video goes into more details, but here are some photos of the site as well.

Sulzer believes the site may be “the biggest secret weapons production facility of the Third Reich.” And, with it being uncovered so many years later, it raises worries of what else the Nazis may have worked on — and hidden — right under our noses.

The excavation team will continue to explore the underground nazi complex and surrounding area to unearth relics that have been buried for decades. Perhaps with more information, they will be able to make further discoveries.
