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.
