The origins of the citadel date back to the 14th century. Initially, a defensive tower structure was built at one end of the bridge to secure access to the Rhône. Over time, this structure was expanded into a full-fledged citadel to defend the city during the Huguenot Wars. The expansion began under the reign of Henry IV and was completed under Louis XIII. The Citadelle de Pont-Saint-Esprit was classified as a monument historique on November 19, 1910, and partially registered on January 18, 1951. Today, some remains of the citadel remain, including the Gothic portal of the former chapel and parts of the walls.
