FROM 1830-1870, Port Arthur was the place the called "hell on Earth," where the convicts of a past era lived and died. With its history of hardship and death, it is no wonder that the grounds and ruins of the Port Arthur convict penitentiary are haunted by multiple apparitions and strange occurences. Strangers from around the world report shockingly similar claims of seeing the same apparitions. Common claims include jail cells with disembodied screams, empty chairs that move, strange footprints and glowing mists. Ghost Hunters International investigate all this. Port Arthur airs Wednesday, January 27th @ 9:00 p.m. EST on The Syfy Channel.
