Tiber Island
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 (642 - 617 BC) by Livy and Dionysius of Halicarnassus.
