History of Si-o-Se-Pol Bridge
Construction of the bridge began in 1599 and ended 1602. Bridge is long 298 meters and wide 13.75 meters. It has 33 spans from which it gets its name with the longest span of 5.6 meters, crosses Zayandeh River and is located in the southern end of Chahar Bagh Avenue.
In 1598 Shah Abbas moved the capital of his Empire from Qazvin to Isfahan – partly because of close proximity to Zayandehrud River, that gave life and nourishment to the city. 5 out of 11 bridges were built during 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.
