Pont du Gard

A 2,000-year-old Roman aqueduct that still stands tall/Bridges & Tunnels

The Pont du Gard is an ancient Roman aqueduct bridge that crosses the Gardon River in southern France. Built in the first century AD without any mortar, its massive limestone blocks are held together purely by friction and precise cutting. It carried water 50 km from a spring to the city of Nimes, dropping only 17 meters over the entire distance, a gradient so gentle it would make a civil engineer weep with admiration. It is the highest of all Roman aqueduct bridges and one of the best-preserved.
