Olde Newgate Prison in East Granby, Connecticut, is notorious for its paranormal activity due to its dark history as both a brutal prison and a treacherous copper mine. Visitors and paranormal investigators report encountering a variety of unsettling phenomena, with many of the hauntings linked to the horrifying conditions prisoners endured underground. Before becoming the first state prison in the United States, the site was a copper mine where prisoners were kept in the dark, cavernous mine shafts. Overcrowding, disease, and torture led to the deaths of numerous inmates, who were buried in unmarked graves. The prison was so inhumane it was known as "Hell" by its prisoners. The history of misery and violence is widely believed to be the source of its lingering hauntings. Both visitors and prison staff have witnessed ghostly figures. Full-bodied apparitions of former inmates and guards have been sighted. An apparition of a man, possibly a former guard named Otto Gufath or warden J.M. Carter, has been seen on the fourth floor of the cell block. Many visitors report feeling a sudden sense of dread, overwhelming anxiety, or nausea, particularly when in the dark, damp mine shafts. These feelings are often attributed to the suffering souls trapped in the former prison. Chilling screams, groans, and other "ethereal voices" have been heard echoing through the underground tunnels. Some claim to hear whispers or the clanking of chains from beyond. Some people have reported feeling like they are being touched, grabbed, or having their clothes tugged by something unseen. The sorrowful ghost of a little girl has reportedly been seen wearing a gray dress in one of the locked cells. She has also been known to tug on visitors' clothes. Unexplained footsteps have been heard on the fourth floor of the cell block. According to one story, a jailer in the 1950s was so unnerved by the sounds that he refused to stay there overnight. Paranormal investigation teams have reportedly captured evidence of cabinets opening and closing on their own.
