Pont du gard roman

The Pont du Gard is a 1st-century AD Roman aqueduct bridge in southern France, renowned for its engineering and preservation.

About this subject

The Pont du Gard is a masterpiece of Roman engineering, built around 19 BC under Emperor Augustus. It was part of a 50 km aqueduct system that carried water from the Eure spring in Uzès to the city of Nîmes (ancient Nemausus). The structure has three tiers of arches, totaling 49 meters in height and 275 meters in length. It is the tallest Roman aqueduct bridge in the world, with stone blocks fitted together without mortar, some weighing up to six tons.

The aqueduct's gradient is remarkably precise: a drop of only 34 meters along the entire route, resulting in an average slope of 0.07%. To ensure watertightness, the inner walls were coated with lime mortar. The Pont du Gard transported about 20,000 cubic meters of water per day, supplying fountains, baths, and homes in Nîmes.

After the fall of the Roman Empire, the aqueduct ceased functioning around the 6th century, but the bridge remained in use as a crossing. It underwent restoration in the 18th century and has been a UNESCO World Heritage Site since 1985. It attracts millions of visitors annually, making it one of the most iconic tourist sites in France.
