The Marne was one of the areas most severely scarred by the First World War, both in the west because of the war of movement with the two battles of the Marne and in the north because of the trench warfare and the fighting during the Argonne and Champagne offensives.
Providing an understanding of the First World War in the Marne is the reason behind this itinerary lined with monuments, ruins, cemeteries and ossuaries, evidence of the fierceness of the fighting, as well as museums which ensure that the First World War, which finished on 11 November 1918, exactly 90 years ago, is never forgotten.
