On a day trip from Montpellier a couple years ago, Kathryn and I spent a winter morning touring the walled city of Aigues-Mortes, France. While the city is a popular stop for tourists, you can tell from the television antennas and satellite dishes in the photo that normal people still live inside these walls, as they have since the Middle Ages.
Also in the upper background of the photo, you can see hills of sea salt in the distance. Sea salt harvesting in the area around Aigues-Mortes has been going on at least since the Middle Ages, maybe longer. For what it’s worth, I’ve seen sea salt from Aigues-Mortes on the tables of unassuming restaurants in France, as well as on the shelves of pretentious boutique groceries here in the States.
