Medieval port city in the Camargue, in southern France. Louis IX (Saint Louis) rebuilt the port in the 13th Century as France's only Mediterranean port at that time. It was the embarkation point of the Seventh Crusade (1248) and the Eighth Crusade (1270). The Constance Tower (1248) is all that remains of the castle built in Louis IX's reign. The city walls were built in two phases: the first during the reign of Philippe III the Bold and the second during the reign of Philippe IV the Fair, who had the enclosure completed between 1289 and 1300.
