Set on the shores of the Rhone River, the skyline of Avignon is like nothing else in France thanks to the picturesque Palace of the Popes, a building that serves as a reminder of the short period of time this city was the seat of the Papacy. Visit the Palace, stroll on the medieval Pont d'Avignon Bridge at sunset and then stay (or at the least stop in for a drink) at the swish Hotel La Mirande and you'll be swept off your feet. Being located in the region of Provence, Avignon is also a great base from which to explore the surrounding area, which in summerfeatures fields filled with lavender.
