Ponte Sublicio

Ponte Sublicio, also known as Ponte Aventino or Ponte Marmoreo, is a bridge linking Piazza dell'Emporio to Piazza di Porta Portese in Rome, in the Rioni Ripa, Trastevere and Testaccio and in the Quartiere Portuense.

The most ancient bridge in Rome crossed river Tiber just downstream of the Tiber Island, in correspondence with the former ford that, during the protohistoric age, was a required stop along the north-south way, at the feet of the Aventine Hill. Its building has been ascribed to King Ancus Marcius by Livy and Dionysius of Halicarnassus.
