The Essex Farm Cemetery is a World War I burial site outside of Ypres, Belgium. There are 1,200 servicemen buried or commemorated here, including 103 unidentified soldiers. Essex Farm was an Advanced Dressing Station during the war, so many of the casualties handled there were laid to rest in this cemetery. Remains of some of the bunkers used for medical services can still be seen near the cemetery. There is also a memorial to the 49th West Riding Division.

John McCrae, a World War I soldier who fought in the Ypres Salient battlegrounds, wrote a poem called “In Flanders Fields” after a friend of his was killed. It is believed that he was in the area of the Essex Farm Advanced Dressing Station when he wrote it. In the poem, he talks about the poppies in Flanders fields, and his short but moving poem became well known. Because of this poem, the poppy has become a symbol of remembrance.
