Khaju Bridge is one of the bridges constructed over the Zayandeh Rud. For its tiled architecture and adornments, it is more famous than any other bridge in Isfahan. Between the eastern and western sides of the bridge, a building has been built with some chambers adorned with paintings. The building is called Shah Neshin and some rulers used to stay there to watch swimming and boating competitions in the artificial lake. A stone bench is all that remained from the throne. In the east corner of Khaju Bridge, there are two stone lions which are the symbol of Bakhtiyari troops who used to protect Isfahan and Zayandeh Rud. The bridge has 24 arches, made by carefully cut cubes and in the center of the arches, there are wooden dams to block the river flow. Khaju Bridge used to be involved in the regulation of river flow. When blocking the river flow, the body of water was elevated to irrigate the gardens.
