Among all of the haunted places of the world, some of the most terrifying are those abandoned, forgotten places with histories of abuse, death, agony, and horror. Such things seem to seep into the very walls of such places to infuse them with some sort of negative energy and paranormal forces, ensuring that they manage to stand out as some of the most intensely haunted places there are. Surely among these must rank the many supposedly haunted prisons of the world, and among these perhaps one of the most haunted of all is a now defunct penitentiary in the U.S. state of Pennsylvania, which has the dark history, bloodshed, and sheer ominous demeanor to make it the perfect setting for terrifying hauntings and all manner of paranormal strangeness.
