Pont du Gard, near NÃ®mes (Roman Nemausus), France. This aqueduct bridge, erected in 19 B.C., carried an estimated 30,000 cubic meters of water daily across the Gardon river. The entire aqueduct stretched 50 kilometers from the water source near UzÃ¨s to the Roman city of Nemausus. After crossing the Pont du Gard (at a height of 49 meters), the water passed over an additional six aqueduct bridges before reaching Nemausus.
