Si-o-se Pol means 33 Bridge or the Bridge of 33 Arches. It is also known as the Allah-Verdi Khan Bridge, one of the eleven bridges of Isfahan, Iran. It is highly ranked as being one of the most famous examples of Safavid bridge design.
Commissioned in 1602 by Shah Abbas I from his chancellor Allahverdi Khan Undiladze, an Iranian ethnic Georgian, it consists of two rows of 33 arches. There is a larger base plank at the start of the bridge where the Zayandeh River flows under it, supporting a tea house.
