HM Prison Dartmoor

HM Prison Dartmoor is a Category C men's prison, located in Princetown, high on Dartmoor in the English county of Devon. Its high granite walls dominate this area of the moor. The prison is owned by the Duchy of Cornwall, and is operated by His Majesty's Prison Service.

In 1805, the United Kingdom was at war with Napoleonic France, a conflict during which thousands of prisoners were taken and confined in prison "hulks" or derelict ships. This was considered unsafe, partially due to the proximity of the Royal Naval dockyard at Devonport , and as living conditions were appalling in the extreme, a prisoner of war depot was planned in the remote isolation of Dartmoor.
The prison was designed by Daniel Asher Alexander. Construction by local labour started in 1806, taking three years to complete. In 1809, the first French prisoners arrived and the prison was full by the end of the year.
