It is certainly the one single building which best represents the lagoon features of the city of Comacchio. It was built in the first half of the seventeenth century, commissioned by Cardinal Pallotta on a plan designed by Luca Danesi from Ravenna. It is formed of five wide rounded staircases, each one extending over one of the canals, topped by a central structure in Istrian stone and two towers. Its purpose was to connect the network of internal canals with the canal leading to the sea. At the foot of the bridge there is a square on which the old fish market was located.
