Marseille, a port city in southern France, has been a crossroads of immigration and trade since its founding by the Greeks circa 600 B.C. At its heart is the Vieux-Port (Old Port), where fishmongers sell their catch along the boat-lined quay. Basilique Notre-Dame-de-la-Garde is a Romanesque-Byzantine church. Modern landmarks include Le Corbusier’s influential Cité Radieuse complex and Zaha Hadid’s CMA CGM Tower.

Montpellier is a city in southern France, 10km inland from the coast of the Mediterranean Sea. The town’s stately Gothic Cathédrale Saint-Pierre, distinguished by conical towers, dates to 1364. The city’s Antigone district is a chic, modern development inspired by neoclassical motifs. Paintings from French and European Old Masters hang at the Musée Fabre.
