Auschwitz-Birkenau Concentration Camp, Oswiecim, Poland

Even without the misty apparitions, unseen but chilling presences, and other unexplainable phenomenon, this spot still packs a wallop of horror, terror, and fright. In the five years of its operations, from 1940 to 1945, the concentration camp has seen over 2 million deaths, a number which most historians consider to be a minimum, owing to the fact that no one can really be sure of the total body count during that most unfortunate time.
Anyone who has set foot in the Auschwitz-Birkenau concentration camp will most likely report a feeling of overwhelming foreboding and melancholy, and given the history of the place, it isn’t so surprising when a visitor suddenly gives in to heart-wrenching sobs and leaves the tour group in a torrent of tears.
There are a number of places on earth that will have your insides quaking with fear, no matter how brave you think you are. Yet, few can compare to the ten most haunted places in the world on this list.
