The Ponte Pietra, once known as Pons Marmoreus, is a Roman arch bridge spanning the Adige River in Verona, Italy. The bridge was completed in 100 BC and the Via Postumia from Genoa to Aquileia passed over it. It is the oldest bridge in Verona. Originally it flanked another Roman bridge, the Pons Postumius; both structures provided the city (on the right bank) with access to the Roman theater on the east bank. The arch closest to the right bank of the Adige was rebuilt in 1298 by Alberto I della Scala. Four arches of the bridge were blown up by retreating German troops in WWII, but rebuilt in 1957 with original materials.
