On October 29, 1891, the new forts built around the cities of Li_ge and Namur, known as the "Forts of the Meuse," were turned over to the Belgian Army.
The huge project, which had begun in 1888 and cost 71.6 million Belgian Francs, required over 9,000 workers to complete. It produced 21 modern forts that could defend the strategic rail, river, and road arteries passing through narrow gaps to the flat, open plains of Flanders. The Forts of the Meuse were the creation of General Brialmont, one of the foremost military engineers of his time. The development of new and more powerful artillery meant that Brialmont's forts were made of concrete, featuring underground barracks, storerooms, and guns protected in revolving steel turrets.
