There is a place near Ypres, Belgium that can give you an eerily accurate idea of how it might have felt to be a World War I soldier in a trench. The place is called Sanctuary Wood (identified as Hill 62 on British military maps), and it is a perfectly preserved, real World War I trench that has gone untouched since 1919. The land where this trench sits is privately owned by the Schier family. And once the Belgian farmer Schier returned to his land in 1919 after the war's end, he kept the trench as it was. It still looks as it did during its time as part of the British front lines: rusted barbed wire, shell holes full of water, shattered trees, and a muddy tunnel system.
