Allāhverdi Khan Bridge (Persian: پل اللهوردیخان), popularly known as Si-o-seh pol (Persian: سی وسه پل; [ˈsiː oˈseh ˈpol], “The bridge of thirty-three spans”) is one of eleven bridges in Isfahan, Iran and the longest bridge on the Zayandeh River with the total length of 297.76 metres (976.9 ft). It is one of the most famous examples of Safavidbridge design.
Built in 1599–1602, the construction was financed and supervised by Allahverdi Khan Undiladze, chancellor of Shah Abbas I, an ethnic Georgian. It consists of two superimposed rows of 33 arches. There is a larger base plank at the start of the bridge where the Zayandeh River flows under it. This supports a tea house which nowadays is abandoned due to drought which some claim is due to government mismanagement.
