The Tiberius Bridge is a great five-arched Istrian stone bridge, which spans the Marecchia River. The river, which was once called Ariminus, lent its name to the city.

Despite the fact that construction work on the bridge began under the rule of Augustus and was only completed by Tiberius (14-21 A.D.), as the inscription sculpted on the inner part of the two parapets states, it is known as Tiberius Bridge and marks the start of Via Emilia.
Its extraordinary solidity and resistance to flooding, a fact that occurs frequently and with great force, are due to the excellent techniques used by the builders and to subtle tricks used by the bridge’s planners (such as the inclination of the pylons, which are laid out in line with the currents). In any case, they have always aroused great wonder and have given rise to the legend of the "devil’s bridge".
The bridge is also noteworthy from an architectural point of view and it is little wonder that it inspired numerous Renaissance artists.
