Fort de la Vitriolerie

Fort de la Vitriolerie is a military fortification in Lyon designed with a triangular layout and two operational sides. The structure contained multi-story barracks arranged to defend the southeastern approaches to the city.

Construction began in 1840 under King Louis-Philippe as part of Lyon's initial defensive perimeter. The fort later played a role in regional military operations and eventually became an administrative headquarters.

The fort was long a symbol of military readiness and defense in the region. Today, its buildings stand as reminders of when this place shaped how the city protected itself.

The site is easily accessible from the city center and can be viewed from the outside. Visitors should walk around the perimeter to appreciate the full scale of the fortification.

The fort was converted to a regional military headquarters in 1968 and continues to serve administrative purposes today. This transformation shows how the old fortification transitioned to new roles while maintaining importance for the region.
