Nomentana Bridge
Nomentana Bridge (Ponte Nomentano) is an ancient Roman bridge in north-eastern Rome that carried the Via Nomentana across the Aniene River. Its central arch dates to the late Republic or early Augustan principate, making it one of Rome’s oldest surviving river crossings; a medieval fortified tower added during the papacy of Nicholas V (1447–1455) transformed it into a distinctive fortified crossing. Today the bridge is restricted to pedestrians and stands within a parkland setting as a protected archaeological monument.

Overview
Ponte Nomentano spans the Aniene River on the ancient Via Nomentana, the consular road connecting Rome to the town of Nomentum (modern Mentana). The bridge is 60 metres long and 7.35 metres wide, with a central arch of 15 metres that retains its original travertine stonework. Its combination of Republican-era engineering and a medieval defensive tower makes it a layered monument spanning roughly two millennia of Roman history.
History
The original bridge was destroyed by the Ostrogoths under King Totila around 547 AD and subsequently rebuilt by the Byzantine general Narses in 552. Pope Adrian I carried out earlier medieval repairs, and Pope Nicholas V undertook a major overhaul between 1447 and 1455 that gave the bridge its distinctive fortified tower. French troops damaged the structure during military operations in 1849, but it was promptly restored. The lateral arches were constructed in brick during the papacy of Innocent X (1644–1655).
What you see
The central arch, built of semi-circular travertine stonework, displays the hallmarks of late Republican or early Augustan construction. Two lateral brick arches added under Innocent X flank the central span. The most striking feature is the medieval tower rising from the bridge’s structure, which served to control and protect this important northern approach to Rome. The entire ensemble is surrounded by parkland and the Aniene valley vegetation.
Cultural significance
Ponte Nomentano is one of Rome’s most intact examples of a Roman road bridge that accumulated successive historical modifications across fifteen centuries. It illustrates the continuous strategic and symbolic importance of river crossings in and around Rome, from Republican road-building programmes through papal urban management to 19th-century military conflicts. The bridge is a listed archaeological monument under Italian heritage law.
Practical information
The bridge is open to pedestrians and free to visit. It is located within a park area along the Via Nomentana in the Montesacro district. No ticket is required. Check official Rome heritage listings for guided tour availability.
Getting there
Take the Via Nomentana north-east from central Rome. Bus routes serving Via Nomentana stop near the bridge. The site is approximately 6 km from Termini station. Cycling along the Aniene riverside path is also a popular approach.
