The Pons Aemilius, also known as Ponte Rotto, is the oldest known stone bridge in Rome. Once spanning the Tiber River, today only a single arch in the middle of the river remains.
History+
Construction of the Pons Aemilius began in 174 BC under Marcus Aemilius Lepidus and Marcus Fulvius Nobilior. Initially, only the bridge piers were made of stone, while the superstructure was constructed from wood. In 142 BC, the bridge was fully equipped with stone arches under Scipio Aemilianus and Lucius Mummius. In the 1st century AD, a restoration took place under Emperor Augustus, who renamed the bridge Pons Maximus.
