Ponte degli Alidosi, Renaissance stone bridge in Castel del Rio, Italy.
The Ponte degli Alidosi spans the Santerno River with a single arch stretching 42 meters in length and rising 19 meters at its peak point.
Construction of the bridge began in 1499 under architect Andrea Guerrieri, commissioned by Obizzo II Alidosi for 500 gold ducats and reached completion in 1519.
The bridge contains five internal rooms that guards used for toll collection, making it an early example of infrastructure combined with administrative functions.
The structure maintains its original design and remains accessible to visitors, situated near walking paths that connect to other historical sites in the region.
The bridge received official recognition as an Italian National Monument through Royal Decree number 535 on November 20, 1897.
