Stonehouse and Devonport are two of the original 'Three Towns' of Old Plymouth. Stonehouse's most interesting landmark is now the Royal William Victualling Yard, a 14 acre site open to visitors. The large Royal Marines Barracks at Stonehouse is an unexpected sight, amidst rows of expensive Georgian houses. Devonport was famous as the city's naval centre. Devonport Dockyard, which once played a very prominent part in the life of Plymouth, still remains the main place in Britain for the refitting of naval vessels and can be visited by the public on Navy Days. Stoke is chiefly a residential area, but Stoke Damerel Parish Church is worth a visit, as it has been a centre for worship for nearly a thousand years.
