“Secrets of the Nazi Occult” takes Expedition X to the Czech Republic, where Phil, Heather, and the team investigate a chilling locale: a castle rumored to be built atop a gateway to hell—a gateway allegedly used by the Nazis. It’s a premise that sounds ripped from an Indiana Jones movie, but the historical backdrop adds an unnerving dose of reality.
The team zeroes in on the area beneath the castle’s chapel, employing their usual mix of scientific instruments and paranormal investigative techniques. They’re looking for any evidence of sinister activity, any trace of the Nazi occult rituals that supposedly took place within the castle walls.
“Expedition X: Secrets of the Nazi Occult” airs Wednesday, February 5, 2025, on Discovery.
