Approach Aigues-Mortes across the flat light of the Camargue and its walls arrive before the town does. The stone line rises from salt marsh and open sky, a complete medieval enclosure that still gives the settlement a clear edge. Inside, lanes lead toward a square; outside, the horizon opens over wetlands and the pale geometry of salt production. Few places make the idea of a frontier feel so visible.
Louis IX—later known as Saint Louis—founded Aigues-Mortes in 1240 as a royal port on the Mediterranean. The kingdom needed a direct maritime outlet, and the settlement offered a point of departure for crusading expeditions. The official town history records Louis’s departure for the Seventh Crusade in 1248 and the beginning of the fortification project in 1266. Construction continued under his successors: the walls were completed under Philip IV in 1285. The result was a carefully planned, almost quadrangular town with monumental gates and defensive towers.
