Yes, this is the place of the "Riverbank" from the previous posting. Pont du Gard in Provence, is the largest preserved ancient roman bridge. It was part of a 50 km long aqueduct, which used to carry water to the city of Nimes. Right above the lowest level of arches is the bridge for crossing. The water was flowing in a closed channel above the top (third) row of arches. Luckily, only a small part of it was destroyed in the middle ages, when most ancient buildings were used as sources of building materials.
