Pons Cestius - Credit: Wikimedia Commons
The Pons Cestius (Latin for the "Cestian Bridge"; ) is an ancient Roman bridge connecting the right bank of the Tiber with the west bank of Tiber Island in Rome, Italy. In Late Antiquity, the bridge was replaced and renamed the Pons Gratiani ("Bridge of Gratian"). It is also known as Ponte San Bartolomeo (Italian for "Bridge of St Bartholomew"). No more than one third of the present stone bridge is of ancient material, as it was entirely rebuilt and extended in the 19th century after numerous earlier restorations. Read more on Wikipedia
