Page "HM Prison Dartmoor" Paragraph 4

Dartmoor Prison was reopened in 1851 as a civilian prison, but was closed again in 1917 to be converted into a Home Office Work Centre for certain conscientious objectors granted release from prison ; cells were unlocked, inmates wore their own clothes, and could visit the village in their off-duty time.

It was again reopened as a prison in 1920, and then contained some of Britain's most serious offenders.
