Pont de Langlois is the drawbridge outside Arles associated with Van Gogh's bridge paintings, although the structure seen today is a later reconstruction moved from the original setting. The appeal is still strong: a simple canal bridge that lets you stand inside one of the artist's recurring Arles motifs.
It is best for visitors already following Van Gogh's trail around town. The site is modest and a little removed from the centre, so treat it as a focused art-history detour rather than a major monument.
