Bodmin Gaol was designed by Sir John Call and built in 1779 by prisoners of war, and was operational for 150 years, in which it saw over 50 public hangings.
The attraction includes original jail cells, an administration block, and a recreation of Bodmin Moor located where the old hospital wing used to be.
Series 6, Episode 1 of Most Haunted, a British-made reality TV show, saw the crew attempt their paranormal activities at the jail with presenter Yvette Fielding and medium, Derek Acorah.
After many unsuccessful attempts, the team supposedly made contact with many light and sound entities, whilst Acorah claimed to have been possessed by a spirit named Kreed Kafer, a South African.
It was later revealed that "Kreed Kafer" was a fictional character, who was created purely by parapsychologist and crew member Ciarán O'Keeffe, to test Derek Acorah and his abilities.
