Ponte Lupo

Ponte Lupo is an ancient Roman bridge made of stone and brick that spans across the Fosso delle Acque Rosse valley. The structure features thick supporting walls designed to carry water through elevated channels.

Built in 144 BC as part of the Aqua Marcia system, the bridge transported water from springs in the Aniene Valley to Rome. This aqueduct supplied the city's growing population for centuries.

The name comes from the Latin word for wolf, referring to the valley's shape that the bridge spans. Locals view this structure as evidence of Roman engineering that shaped daily life in the ancient city.

Access is through an unmarked trail starting from Via Polense near the intersection with Via Faustiniana in Gallicano nel Lazio. The terrain is uneven and natural, so sturdy footwear and time to explore at your own pace are recommended.

The structure uses artificial channels carved directly into the tuff cliffs on either side of the valley to efficiently convey water across difficult terrain. This overlooked solution shows how Romans masterfully combined natural features with engineering ingenuity.
