The bridge connecting the Tiber Island with the Jewish Ghetto is the most ancient in Rome. Its original name is Ponte Fabricio and it was built more than 2000 years ago.
During the 16th century Pope Sixtus V commissioned to 4 architects the restoration of the ancient bridge. The four architects were not good friends and ended up in many fights. When the bridge was restored the Pope decided to kill them because they didn’t behave in a Cristian way. They were beheaded on this bridge and in their honor a head with four faces was carved.
The four architects are now obliged to stay near to each other for the eternity and the Roman people still call this bridge Ponte dei 4 Capi.
