Frederick J. Kolb, an American geologist, traveled to Iran several times between 1306 and 1316 and left an attractive photo album.

In a part of the photos related to the city of Isfahan, Jay Kalb recorded an interesting image of the Zainderoud river and thirty-three bridges, which shows a historical situation of this region.

Thirty-three bridges or Allahwardi Khan Bridge, dating back to the reign of Shah Abbas I Safavid, were built on the Zayandeh River under the supervision and at the expense of the famous Safavid general, Allahwardi Khan. The construction of the thirty-three bridges was proposed in 1008 AH and in the twelfth year of the reign of Shah Abbas I, and in 1011, Allahwardi Khan Ondiladze Georgia was commissioned to complete it.
