Si-o-se Pol
Road Historic Safavid-era bridge in Isfahan with 33 arches
Across Isfahan’s Zayandeh River Si-o-se Pol (the Bridge of 33 Arches) links riverbanks with long pedestrian spans and evening tea stalls. Visitors gather for night views, traditional promenades and nearby bazaars.
Si-o-se Pol, literally “Bridge of 33 Arches,” is a Safavid-era bridge in Isfahan, Iran, spanning the Zayandeh River and renowned for its rhythmic series of arches. It is one of Isfahan’s most famous bridges and a regular focal point for both local life and visitors.
The structure’s long arcade of 33 arches and broad pedestrian walkway provide opportunities for walking along the river and for photography of the repeated architectural sequence. The bridge functions as both a traffic crossing and a social space, with strong visual presence when water is in the river below.
Construction dates to the early 17th century during the Safavid period under the rule of Shah Abbas I, and the bridge has been maintained and restored at various times since then. Its combination of utility and ornamentation exemplifies Safavid urban planning and river management in Isfahan.
Si-o-se Pol sits in central Isfahan, crossing the historic Zayandeh River within the city’s older urban fabric and near major avenues and gardens of the city centre.
- Structure and scale: Composed of 33 arches and measuring roughly 295 to 300 metres in length, it is a prominent example of Safavid civil engineering in Isfahan.
- Viewing and river conditions: Flows on the Zayandeh River are seasonal and subject to variation; the bridge is visually striking at dusk and during periods when the river is flowing.
