The Old City Jail ("Gaol") in Charleston, South Carolina was built in 1802 right over the Provost Dungeon and a potter's field. It also served as an insane asylum and housed Union soldiers (prisoners of war). Why is this site considered so haunted? Is it due to the on-site death toll (estimated to be anywhere between 10,000 and 14,000)? Is it due to the deplorable conditions? Or perhaps some of its famous inmates? Jamie Davis, author of Haunted Asylums, Prisons, and Sanatoriums, went to explore.
In a little town called Medfield, Massachussetts, Jamie Davis and Sam Queen (co-authors of Haunted Asylums, Prisons, and Sanatoriums) came upon the abandoned Medfield Insane Asylum. Used for location in the film Shutter Island, Jamie and Sam could only imagine what awaited them within the many buildings, all in various stages of degradation.
