Ponte Rotto
The Rotto Bridge was built in 214 BC, by Manlio Emilio Lepido, and was the first masonry bridge in the city of Rome. Also known as 'Pons Aemilius', it changed its name many times over the centuries. The 1598 flood destroyed three of the six arches and the bridge was no longer rebuilt. Currently, there is only one sixteenth-century arch left, resting on the original pylons of the 2nd century BC.
