Si-o-seh bridge


The 298m-long Si-o-Seh Bridge was built by Allahverdi Khan, a favourite general of Shah Abbas I, between 1599 and 1602 to link the upper and lower halves of Chahar Bagh St. It served as both bridge and dam, and is still used to hold water today. Until recently there were teahouses at either end of the bridge, both accessed through the larger arches underneath, though only the northern one remains.
