On the cusp of the Camargue National Park in the Provence-Alpes-Côte d’Azur region, Arles is a heady blast of Van Gogh nostalgia – the artist painted in excess of 200 works around this lovely Roman town. The stately amphitheatre, one of the largest in Roman times, is part of the reason for Arles’ Unesco World Heritage Site status. The twisting aluminium tower designed by Frank Gehry brings the city’s architecture bang up to date.
