Fort de Charenton

Fort de Charenton is a fortified installation in Maisons-Alfort designed according to the Vauban defense system with multiple barracks areas spread across its grounds. The structure was strategically positioned to help defend the approaches to Paris and remains largely intact from its original construction.

The fort was built between 1841 and 1845 as France sought to strengthen the defenses around Paris following the occupation after Napoleon's defeat. It formed part of a broader ring of sixteen fortifications designed to protect the capital from future invasions.

The fort functions as a training and command center for France's gendarmerie schools and Republican Guard, making it a place where military traditions and modern policing methods continue to evolve. This role connects the old stone walls to the daily work of those who serve the country today.

Access to the site is typically restricted due to its active use by military and law enforcement institutions. Plan a visit during Heritage Days events when the fort opens to the public, or contact local authorities in advance for permission.

During World War II, specialist Henri-Marcel Francois saved the fort from destruction by defusing explosive devices planted by German troops in 1944. This courageous action preserved one of the major defensive structures surrounding Paris from being lost.
