Marseille, France

Founded in 600 BC, Marseille is the oldest city in France and its third largest metropolitan area. A must-see is the 19th-century basilica, Notre Dame de la Garde, which sits at the highest point in the city. Also worth a visit is the water fountain at Palais Longchamp, built under the reign of Napoleon III. Marseille is considered the birthplace of bouillabaisse, so make time to stop for a bowl of this famous seafood stew in the Old Port. You might also wish to drive through the Provençal countryside to Aix-en-Provence, a charming town best known as the home of impressionist painter Paul Cézanne.
