Near the Palais des Papes, this majestic 12th-century cathedral contains the elaborate tombs of popes Jean XXII and Benoît XII. Crowning the top is a 19th-century gilded statue of the Virgin. From the cathedral, enter the Promenade du Rocher-des-Doms to stroll its garden and enjoy the view across the Rhône to Villeneuve-lez-Avignon.
