Origin and history

Écouen Fort, located in Val-d'Oise, is part of the second belt of fortifications built around Paris after the French defeat of 1871. This defensive system, designed under the direction of General Séré de Rivières, was designed to protect the capital against possible invasions. The fort, of polygonal shape, was equipped with a double caponière and three simple caponières, which could accommodate 335 soldiers and 22 cannons. It was supplemented by a battery and dread, now missing or damaged.

Ranked a Historical Monument in 2007, the fort illustrates the military architecture of the late 19th century, marked by the adaptation to the progress of artillery. Its plan meets the standards set by Séré de Rivières, combining defensive efficiency and integration into the landscape. Parcel A1 162, on which it is implanted, is protected in its entirety, including soil.

The site, although disused of its military use, retains a major heritage value. The available GPS coordinates suggest a precise location, and its official address is listed in the Merimée database. No information is provided on its current accessibility (visits, rental, accommodation), but its ranking shows its historical and architectural importance.
