Musée Réattu Arles

This superb 150-year-old museum, housed in an exquisitely renovated 15th-century Hospitaller priory by the Rhône, might be assumed old-fashioned, yet its modern collection is truly top-notch. Among its holdings are works by 18th- and 19th-century Provençal artists, two paintings and 57 sketches by Picasso, and of course some works from its namesake, Jacques Réattu. It also stages wonderfully curated cutting-edge exhibitions.
