The town of Aigues-Mortes was deliberately built on reclaimed swamp land to create a royal port for the French monarchy.
The Constance Tower served as a prison for Huguenots during the 18th century, with 'Résister' carved into the stone by prisoner Marie Durand.
Unlike most medieval cities that grew organically, Aigues-Mortes was planned on a strict gridiron street pattern.
The walls were constructed over several decades by both Louis IX and his son, Philip the Bold.
The name Aigues-Mortes translates to 'Dead Waters,' referring to the stagnant marshes that surrounded the town.
The ramparts have survived without ever being breached in a military siege.
The site acts as a geological boundary between the freshwater marshlands and the man-made pink salt pans of the Salin du Midi.
The Towers and Walls of Aigues-Mortes encompass a perfectly preserved rectangular medieval fortification system surrounding the historical center of a town founded by Louis IX in the 13th century. The ramparts stretch 1,600 meters in length and feature ten gates and five towers, including the prominent Constance Tower. Originally serving as France’s first Mediterranean port, the site provided a strategic embarkation point for the Crusades. Visitors can walk the entire perimeter of the ramparts to view the surrounding Petite Camargue marshlands and salt pans. The stone structures are composed of locally sourced limestone, showing minimal alteration since the Middle Ages. The site is managed by the Centre des monuments nationaux and maintains its original military architecture, including crenellations and arrow slits. It remains one of the few examples of a complete medieval curtain wall still standing in Europe.

Wear sturdy, closed-toe walking shoes, as the rampart pathways are uneven and composed of ancient stone.
Bring a hat and sunglasses, as there is almost no shade along the top of the fortification walls.
Visit the interior of the Constance Tower separately, as it contains historical exhibits not visible from the wall walk.
Avoid walking the ramparts during high wind alerts, known locally as the Mistral, as the elevated walkways are fully exposed.
Open year-round but may have limited access during extreme high wind events; check official monument site for localized closures.
Maintain respectful behavior in areas designated as former prisons; avoid climbing on parapets or loose stonework.
