Lying just in front of the German front line, and partially straddling the site of a strongpoint, the Heidenkopf or Quadrilateral, Serre No.2 contains 7,127 Commonwealth graves, of which 4,944 are unidentified, the highest proportion of any British & Commonwealth cemetery in France. Most are from the unsuccessful attacks of 1st July and 13th November 1916, though the cemetery also contains many graves from the subsequent consolidation of smaller burial sites. It was designed by Sir Edwin Luytens, and completed in 1934.
