The Arles Office of Tourism website offers a comprehensive view of the ancient sites, museums, exhibitions, events, markets, festivals, and general goings on in Arles.
Van Gogh Route is a wonderful website that maps out where the artist lived and created. Organized by city, each interactive map plots out the sites depicted in his paintings.
In 2015 the Fondation van Gogh renovated a mansion close to the Place du Forum and entered a partnership with the Van Gogh Museum in Amsterdam, who now lends paintings by the artist regularly. I’m happy there is now an opportunity to see his work in Arles, and perhaps even a painting or drawing he created there.
