The Pont du Gard, an extraordinary Roman aqueduct bridge in the South of France, stands as one of the finest examples of ancient engineering and a UNESCO World Heritage site. Built in the first century AD, this impressive three-tiered structure once transported water over 50 kilometers to the city of Nîmes, showcasing the ingenuity and skill of Roman architects. At 49 meters high, it remains the tallest Roman aqueduct bridge in the world, with its massive stone arches stretching gracefully across the Gardon River.
