The granite church stands near the middle of Dartmoor, above sea level in an exposed location close to Dartmoor Prison. Permission for the construction of the church was given 1812 by the Lord Commissioners of the Admiralty. The church was designed by the architect Daniel Alexander and built by prisoners from the Napoleonic Wars and finished by those captured during the American war who were held in the prison, and is the only church in England to have been built by prisoners of war.
