Designed by Sir Herbert Baker, it is the largest British war cemetery in the world with 11.871 graves and 34,926 names of those killed Aug 1917 - Nov 1918 and who have no known grave. The original cemetery with 350 graves was based around a pill box which now forms the base of the Cross of Sacrifice: this was a German bunker which was then turned into an Aid Post.
