The Ponte Pietra or the Pons Marmoreus, the Roman arch bridge crossing the Adige River in Verona, is located in one of the most panoramic and suggestive sites in Verona. The bridge was completed in 100 BC, and has undergone several reconstructions since then.
An initial bridge across the Adige, perhaps in wood, may have been built in this site following the construction of the Postumia Road, which ran from Genoa to Aquileia, in 148 B.C. Both structures provided the city (on the right bank) with access to the Roman theatre on the east bank. When the Adige was in spate, or through the intervention of man, the bridge collapsed in 1007, 1153 and 1232 and 1239. In 1503 the bridge was rebuilt in stone, but collapsed and was rebuilt in wood. On 25 April 1945, four arches of the bridge were blown up by retreating German troops in World War II, but rebuilt in 1957 with original materials.
The bridge blown up by the Germans had five arches of different sizes: the two towards the left bank of the Adige were Roman and built of stone; of the other three, the one closest to the right bank was still the one built in 1298, while the other two had been rebuilt in 1520.
In the Roman part there were apertures similar to elongated windows. A round hole was located above the third piling, in the middle of the bridge.
As such, the stone bridge in Verona reflects a unique history of reconstruction from different époques.
