Near the Provençal city of Arles, contemplate two incredible feats of engineering: an ancient Roman viaduct and a 21st-century cable bridge taller than the Eiffel Tower. Stop at the “monarchist” village of Les Baux-de-Provence; then view the Gallo Roman architecture of Arles, see the sites that inspired Vincent Van Gogh, and discover Arles’ lavender fields and local food specialties.
