While in Aix-en-Provence, you must visit a provincial market. And Le Grand Marché refers to the many markets that flood the city's squares: You'll find fresh food and sweet treats in Place des Prêcheurs and Place de la Madeleine, gorgeous garments in the clothing market on the Cours Mirabeau on Tuesdays and Thursdays (it's around the Palais des Justice on Saturdays), a flea market around the Place de Verdun and a flower market at the Place de l'Hôtel de Ville.

Keep in mind that these markets are only open Tuesdays, Thursdays and Saturdays (typically in the morning) and hours vary.
