Shahrestan bridge is the oldest bridge on Zayanderud River in Isfahan. It connects the village of Shahrestan on the north side with the agricultural area on the southern bank. The foundations are from the 3rd to 7th century Sassanid era, but the top was renovated in the 10th century by the Buyids and finally during the 11th century Seljuq period. However the architectural style is totally Sassanid. The bridge was built in two parabolic shapes. The vertical parabolic component means that the middle point of the bridge is the highest part. The horizontal parabolic produces a bend to the west strengthening it against the flow of the river. This bridge is 107.8 meters long and an average of 5.2 metres wide.
