Fort de la Double-Couronne, Military fortification in Saint-Denis, France.
Fort de la Double-Couronne was a military fortification in Saint-Denis that stretched about 1,150 meters in a half-moon shape. An elevated pathway connected it to the nearby Fort de la Briche, creating a connected defensive line.
The fortress served as an artillery position during the 1870-1871 Siege of Paris, holding 74 heavy guns. After World War I, the fortification was demolished and the site was later developed with new buildings.
The fort helped protect the industrial growth of Saint-Denis in the 1800s by controlling access to main roads in the area. It was part of a larger defense system that watched over the city and its expanding factories.
The site is now occupied by residential buildings, sports facilities, and a bus center, so it is not open as a traditional tourist attraction. You can walk around the area and get a sense of where the fortification once stood.
A major explosion occurred on the site on March 4, 1916, which led to an important legal decision. The State Council later ruled that the military had to compensate nearby residents, even though no fault could be proven.
