The existing Khaju Bridge was built by order of Shah Abbas II in 1655 A.D. It is the only bridge over the Zayandeh Rood river with polychrome tiles decoration. Khaju is derived from the word Khajeh which is a title for courtiers and those close to the royal family and since they lived near this bridge, the area and the bridge itself are called Khaju. It is a double decker bridge. The top storey was used for caravans to pass over with covered corridors for pedestrians on both sides and the lower storey was specifically for pedestrians only and a place for leisure and recreation. Khaju Bridge is 133 meters long and 12 meters wide.
