The Pont d'Aël is a Roman aqueduct bridge located near the village of the same name in the municipality of Aymavilles, in the Aosta Valley. It was built in 3 BC for the irrigation and supply of a mineral washing plant for the colony of Augusta Praetoria Salassorum, today's Aosta, then just founded. The bridge, located at the entrance to the Cogne valley, a side valley, 66 meters above the valley floor, supports a technically advanced aqueduct, a total of 6 km long.
