In the summer months, when the Tiber is low, it is possible to see the remains of the ancient Pons Neronianus (Bridge of Nero).
Although the bridge is named after the emperor Nero (r. 54-68), it may have been erected during the reign of Caligula (r. 37-41), who built a circus on the site where St Peter's Basilica now stands.
