Khaju Bridge

khajoo

Khaju Bridge is a bridge in the province of Isfahan, Iran, which has been described as the finest in the province. It was built by the Persian Safavid king, Shah Abbas II around 1650, on the foundations of an older bridge. Serving as both a bridge, and a dam (or a weir), it links the Khaju quarter on the north bank with the Zoroastrian quarter across the Zayandeh River. Although architecturally functioning as a bridge and a weir, it also served a primary function as a building and a place for public meetings. This structure was originally decorated with artistic tilework and paintings, and served as a teahouse. In the center of the structure, a pavilion exists inside which Shah Abbas would have once sat, admiring the view. Today, remnants of a stone seat is all that is left of the king’s chair. This bridge is one of the finest examples of Persian architecture at the height of Safavid cultural influence in Iran. In words of Upham Pope and Jean Chardin, Khaju bridge is “the culminating monument of Persian bridge architecture and one of the most interesting bridges extant…where the whole has rhythm and dignity and combines in the happiest consistency, utility, beauty, and recreation.

Band-e Kaisar

Shushtar

The Band-e Kaisar (“Caesar’s dam”‎‎), Pol-e Kaisar (“Caesar’s bridge”), Bridge of Valerian or Shadirwan was an ancient arch bridge in Shushtar, Iran, and the first in the country to combine it with a dam. Built by a Roman workforce in the 3rd century AD on Sassanid order, it was also the most eastern Roman bridge and Roman dam, lying deep in Persian territory. Its dual-purpose design exerted a profound influence on Iranian civil engineering and was instrumental in developing Sassanid water management techniques.

The approximately 500 m long overflow dam over the Karun, Iran’s most effluent river, was the core structure of the Shushtar Historical Hydraulic System from which the city derived its agricultural productivity, and which has been designated by the UNESCO as Iran’s 10th World Heritage Site in 2009.

Many times repaired in the Islamic period, the dam bridge remained in use until the late 19th century.

Shahrestan Bridge

shahrestan

Shahrestan bridge is the oldest bridge on Zayandeh Rud in Iran. The foundations are from the 3rd to 7th century Sasanian era, but the top was renovated in the 10th century by the Buyids and finally during the 11th century Seljuk period. However the architectural style is totally Sasanian. The bridge was built in two parabolic shapes. The vertical parabolic component means that the middle point of the bridge is the highest part. The horizontal parabolic produces a bend to the west strengthening it against the flow of the river. This bridge is 107.8 metres long and an average of 5.2 metres wide. It has two levels of arches, 13 in the bottom and 8 on the top. The higher sluices quickened the passage of water during floods, thus taking pressure away from the structure. About 100 metres away from the bridge, the Zayandeh Rud has recently been diverted towards the south and an artificial lake has been established around the bridge to protect it from further damage.
