Fort d'Ivry, Montreuil

Fort d'Ivry was built in the Paris suburb of Ivry-sur-Seine between 1841 and 1845, as one of the forts in a ring of strong points surrounding Paris. The fort is about 1 kilometre outside the Thiers Wall, built by the same program in response to a perception that Paris was vulnerable to invasion and occupation. The fort was upgraded in the 1870s, to cope with improvements in artillery performance as part of the Séré de Rivières system. In 1946, the fort was vacated by the garrison. It is now the home of the Communication and Audiovisual Production Company for the Department of Defense. ()
