Fort de Condé-sur-Aisne, Military fortification and museum in Condé-sur-Aisne and Chivres-Val, France.
Fort de Condé is a five-sided masonry structure near Condé-sur-Aisne and Chivres-Val in France. The thick stone walls enclose several underground levels including ammunition chambers, an infirmary, and quarters for the garrison.
Construction began in 1877 and ended in 1883 as part of the Séré de Rivières defense system between Soissons and Laon. During the First World War, control shifted between armies until France reclaimed it in 1917.
The casemates still bear wall inscriptions left by German and French soldiers from several war years. Inside the rooms, original weapons and equipment show how garrison troops lived underground here.
The site lies off main roads and is easiest to reach by car. The underground passages stay cool, so warm clothing helps even in summer.
Some sections served as a quarry after the war and were only secured for visits later. The stone walls still show marks from artillery fire during the fighting.
