How can the magic of Arles be explained? Does it come from the distinctive light that once so dazzled Van Gogh? The impressive architectural vestiges that are the legacy of successive generations? Or from its hotchpotch of cultures? Camargue and Provence, Gypsy and Parisian, agricultural and intellectual, Arles lies at the intersection of France's different southern regions. More than a city, Arles is a state of mind, which reveals its even more ebullient self during the ferias.
