Nimes, France - September 11, 2010: a view of the Pont du Gard. The Pont du Gard is an ancient Roman aqueduct that crosses the River Gardon in the south of France. Located near the town of Vers-Pont-du-Gard, the bridge is part of the Nîmes aqueduct, a 50-kilometer system built in the first century AD to carry water from a spring at Uzès to the Roman colony of Nemausus (Nîmes). The bridge has three tiers of arches, standing 48.8 m (160 ft) high. The whole aqueduct descends in height by only 17 m (56 ft) over its entire length, while the bridge descends by a mere 2.5 cm (0.98 in) – a gradient of only 1 in 3,000 – which is indicative of the great precision that Roman engineers were able to achieve, using only simple technology. The aqueduct formerly carried an estimated 200,000 m3 (44,000,000 imp gal) of water a day to the fountains, baths and homes of the citizens of Nîmes.
