This aerial shot shows the trenches of the Main de Massiges, still a scar on the landscape of this small rural community in the Marne department in north-eastern France.

The trenches sit on the crest of a hill and were a hugely important strategic point on the Champagne Front after the Germans retreated here during the Battle of the Marne in 1915. Volunteers began restoring the trenches in 2012, uncovering wine bottles, boots, scrap metal and even human remains.
