Paris Catacombs– Paris, France
Perhaps the most terrifying-looking place on the list, the Paris Catacombs would be scary even without paranormal activity. Filled with relocated bones from overcrowded cemeteries, the artful arrangement of the bones do seemingly nothing to prevent the discontented spirits to roam the catacombs. Visitors have reported being pushed and shoved, and some people have even reportedly disappeared after entering the catacombs, never to be found again.
