Fort du Haut-Buc

Fort du Haut-Buc stands at 160 meters altitude on the Saclay plateau, featuring a trapezoidal architecture with multiple defensive structures and underground passages.

Constructed between 1874 and 1880 as part of the Séré de Rivières defense system, the fort was designed to accommodate 820 soldiers and 56 artillery pieces.

The fort represents French military engineering from the late 19th century, with its design reflecting the strategic response to the Franco-Prussian War defeat.

The site remains closed to public access as it serves as a training ground for law enforcement and maintains restricted military status.

Two bread ovens capable of producing 226 rations each supplied the garrison, while a 525-cubic-meter cistern provided water storage without a well.
