At the time of its construction, Fort des Ayvelles, controlled Meuse and the railway line linking what city in the Grand Est region of France, that lies 129 km east-northeast of Paris?
Fort des Ayvelles The Fort des Ayvelles, also known as the Fort Dubois-Crancé, is a fortification near the French communes of Villers-Semeuse and Les Ayvelles in the Ardennes, just to the south of Charleville-Mézières. As part of the Séré de Rivières system of fortifications, the fort was planned as part of a new ring of forts replacing the older citadel of Mézières with dispersed fortifications. With advances in the range and destructive power of artillery, the city's defensive perimeter had to be pushed away from the city center to the limits of artillery range. The Fort des Ayvelles was the only such fortification to be completed of the ensemble, as resources were diverted elsewhere. At the time of its construction the fort controlled the Meuse and the railway line linking Reims, Montmédy, Givet and Hirson. The Fort des Ayvelles was reduced in status in 1899, its masonry construction rendered obsolete by the advent of high-explosive artillery shells. However, it was re-manned for the First World War before it was captured by the Germans on 29 August 1914. The fort was partly destroyed in 1918. During the Battle of France in 1940 the fort was bombarded. French resisters were executed at Ayvelles during both world wars. At present the fort is maintained by a preservation society, and may be visited.
Seine–Nord Europe Canal The Seine–Nord Europe Canal is a projected high-capacity ("grand gabarit") canal in France that would link the Oise River at Compiègne with the Canal Dunkerque-Escaut, east of Arleux. The objective is to expand trade flows in a fuel-efficient and ecologically friendly manner between the Seine basin and Belgium, Germany and the Netherlands, while reducing saturation on the A1 motorway in France and reducing the CO2 emissions in the transport sector within this corridor.
