Birr Cross Roads was named by the 1st Leinsters from their depot. The cemetery was begun in August 1917 and used as a Dressing Station cemetery until, and after, the German advance in 1918. At the Armistice, it contained nine irregular rows of graves, now part of Plot I, but was greatly enlarged when graves were brought in from the surrounding battlefields and from smaller cemeteries. The cemetery was designed by Sir Edwin Lutyens.
