Zone Rouge – or the “Red Zone” – is a chain of former battlefields across northeastern France that the government has cordoned off due to the many dangerous ordnance that remains from the First World War. The area originally spanned over 460 square miles, from Nancy through to Lille, and incorporates such battlefields as the Somme, Verdun and Vimy Ridge.
While the size of the region has lessened over the 100-plus years since the end of the conflict, the area is still characterized by the scars and remnants of the Great War.
