Lyness Royal Naval Cemetery
Scapa Flow was a Royal Naval base during both the First and Second World Wars.
Sailors began burying their fallen comrades at Lyness in Hoy in 1915 and the cemetery remained in use until 1946, by which time the navy had scaled back its operations in Orkney.
Among those laid to rest here are more than 440 Commonwealth servicemen of the First World War, nearly all sailors, of whom 107 remain unidentified.
Alongside them are the graves of 13 sailors of the German High Seas Fleet dating from November 1918 to June 1919.
