Pont d'Aël Roman Aqueduct

The Pont d'Aël is a Roman aqueduct bridge in the village of the same name, in the comune of Aymavilles, in Aosta Valley, Italy. The bridge, constructed in 3 BC, carried water for the agricultural lands of the newly founded colony Augusta Prætoria Salassorum (today: Aosta) across a side valley, 66 m above the bottom. It belonged to a sophisticated, 6 km long aqueduct, running along the steep cliffs of the valley. The originally three-story structure featured a roofed control corridor; notably, it was privately financed. Today, the Pont d'Aël carries a hiking trail.

Besides the Pont d'Aël, two other Roman bridges in the Aosta valley are still intact: the Pont-Saint-Martin in the town of the same name and the Pont de Pierre in Aosta.
