The current prison buildings are Victorian, built in 1868 but there has been a prison on that site since 1793. The prison was decommissioned by the Ministry of Justice in 2013 and is now open to the public as a tourist attraction offering a variety of tours including guided and self-guided
The guided tours are led by ex-prison officers who showcase just what life was like, day and night, for prisoners, officers and visitors. During the two hours they shine a light on what really happened, from the Victorians to the 21st century, behind the high prison walls. Tours take in two wings (one is particularly haunted) the exercise yards, the segregation cells, healthcare and the execution room including the condemned man’s cell and the executioner's room.
