Tyne Cot Commonwealth War Graves Cemetery and Memorial to the Missing is a Commonwealth War Graves Commission (CWGC) burial ground for the dead of the First World War in the Ypres Salient on the Western Front. The cemetery grounds were assigned to the United Kingdom in perpetuity by King Albert I of Belgium in recognition of the sacrifices made by the British Empire in the defence and liberation of Belgium during the war. It is the largest cemetery for Commonwealth forces in the world, for any war.
