It's located on the western edge of the Camargue, a natural area between the Mediterranean Sea and the two arms of the Rhône River delta. It was built by Louis IX as a 'jumping-off point for his Crusades to the Holy Land'. Ironically, it's not on the sea; it was connected to the sea by canals.
Within the walls we came across a church with very unusual stained-glass windows that gave the place a most unusual light quality.
We also discovered charming streets full of souvenir shops. While many were very tacky, some were most impressive, selling a variety of gourmet foods, biscuits, olive oil, and chocolates designed to look like olives.
