Long associated with Van Gogh who produced hundreds of paintings there, the UNESCO World Heritage city of Arles on the Rhone river in Provence also has some of the finest Roman ruins in France. The well-preserved ampitheater is still used for bullfights today, while the partially-restored Roman theater is once again in use as well. Not far away, the rocky hilltop town of Les Baux looks like an otherworldly movie set.
