Ploutonion (Cave of Charoneia)

What the Show Claims

• ›Ancient Astronaut theorists propose that this toxic cave in Turkey, described by ancient Greeks as a physical gateway to Hell, may represent an actual stargate or interdimensional portal used by extraterrestrial beings for travel.

What Archaeology Says

The Ploutonion is a real archaeological site near Hierapolis in modern-day Turkey. Ancient Greeks described it as an entrance to the underworld due to toxic volcanic gases that emanate from the cave, which were lethal to animals and humans. It is not a gateway to Hell but rather a natural geological phenomenon with toxic vapors.
