Si-o-Se-Pol, also known as Allahverdi Khan Bridge, is one of the eleven Isfahan bridges, crossing Zayandehrud River. It is the most famous bridge of Isfahan due to its size, central location, and prominent architecture. The bridge is a center of city nightlife that attracts both Iranians and foreign tourists.

The bridge was built between 1599 and 1602 during the reign of Shah Abbas. The construction process was controlled by Shah’s chancellor, Allahverdi Khan Undiladze – that is where the second name of the bridge derives from.

In 1598 Shah Abbas moved the capital of his Empire from Qazvin to Isfahan – partly because of close proximity to Zayandehrud River, which gave life and nourishment to the city. 5 out of 11 bridges were built during the Safavid era as the means of crossing the river. During 400 years of history of the bridge the river dried up, but Si-o-Se-Pol found other purposes. It was a place for evening walks, public meetings, events, an observation point for regattas, and other water sports.
