The Ponte Pietra, formerly known as the Mons Marmoreus, which crosses the Adige River, is one of the most important monuments of the Latin colony of Verona: of the two Roman era bridges this is the only one that remains. The brick tower, intended for the defence of the bridge, was built at the time of the condottiero Alberto I della Scala (1298). The five arch bridge, has been rebuilt at various times following its collapse in different materials, with the Roman sections in stone. The most recent repair was in consequence of its deliberate destruction, in the path of the German army's retreat through Northern Italy.
- 1508 - The City Council asked the Architect Fra’ Giocondo to superintend the reconstruction of the Roman bridge.
- Its reconstruction between 1957 and 1959 is faithful to the destroyed bridge.
