Description: Aigues-Mortes is a town and commune in the Gard département, in southern France, famous for the well-preserved city walls surrounding the city.
The foundation of the city is attributed to Marius Caius, around 102 BC, but the first document mentioning a place called "Ayga Mortas" (dead waters) dates from the 10th century.
Louis IX of France (Saint Louis) rebuilt the port in the 13th century and had the new fortifications added to get the city secured as well from ennemies than from bad weather. Typical of some military buildings of the era, the keep (Tour "Constance") is built outside on the main enclosure as a separate stronghold point.
In those days, the city was still on the bank of Mediterranean sea and was the embarkation point of the Seventh and the Eighth crusades.
