The Fort de la Pompelle, also known as Fort Herbillon, is one of a number of forts built around Reims after 1870 as part of a fortification belt in the Séré de Rivières system. The forts saw combat during the First World War in the defense of Reims. The fort is located about north of the town of Sillery, next to the N44 road, between Reims and Châlons-en-Champagne. Constructed as a supporting position for larger forts and disarmed in 1913, it saw the heaviest fighting of the Reims forts. It was bombarded during the war and remains in a state of ruin.
