Pluto’s Gate, Turkey
It’s easy to understand why individuals in the past thought that Ploutonion in Hierapolis, also known as Pluto’s Gate, was a perilous location that may result in one’s death. It was constructed on top of a cave that was a sacred passageway to the underworld and produces deadly vapors, including high quantities of carbon dioxide. The fact that it was created as a religious site dedicated to the god Pluto and used as a ritual passage to the underworld seems fitting because, in 1965, scientists confirmed that it had been built on top of the cave.

Morgan Island, South Carolina
The island of Morgan, located in South Carolina, is sometimes referred to as “Monkey Island” due to the presence of four thousand rhesus monkeys on the island. The monkeys are not indigenous to the area; rather, they were transported over from Puerto Rico when an epidemic of herpes virus B occurred here. Morgan Island is now closed to the public for both security reasons and for the welfare of the island’s monkey species.
