3 Best Sights in Provence, France

Across from a commercial gallery that calls itself the Petit Musée Cézanne (actually more of a tourist trap), this 17th-century mansion once hosted Louis XIV—and now houses government offices. This means that during business hours you can slip in and peek at the fabulous 18th-century stairwell, decorated in flamboyant trompe-l'oeil. Pseudo-stone putti and caryatids pop into three dimensions—as does the false balustrade that mirrors the real one in stone.

Vestiges of the Renaissance remain in Les Baux, including the pretty Hôtel de Manville, built at the end of the 16th century by a wealthy Protestant family. Step into its inner court to admire the mullioned windows, stained glass, and vaulted arcades. Today it serves as the mairie (town hall). Up and across the street, the striking remains of the 16th-century Protestant temple still bear a quote from Jean Calvin: "post tenebras lux" ("after the shadows, light").

Built between 1655 and 1678 by Pierre Pavillon, the Hôtel de Ville is fronted by a pebble-encrusted courtyard set off by a wrought-iron gateway. At the back, a double stairway leads to the Salle des Etats de Provences, the old regional assembly room (where taxes were voted on), hung with interesting portraits and pictures of mythological characters. From the window, look for the unmistakable 16th-century clock tower with an open ironwork belfry. The tree-lined square in front—where cafés set up tables right into the center of the space—is a popular gathering place.
