What is Gerdab-e Sangi?

Gerdab-e Sangi is a building with a diameter of 18 meters and a width of 3 meters and a height of 12m. The structure of has been built around a seasonal well. This well feeds the Gerdab-e Sangi and it has water only from mid-winter to mid-summer. It was one of the oldest springs of the Sassanid era, and the water was channeled from here to the city of Shapurkhast using the channels surrounding it. Shapour Khast was, in fact, a Sasanian city located in the current location of Khorramabad city.

On the east side of this rocky structure, there is a small, beautiful lake. A sliding block allows the water to flow easily from here to the channels on the other part. This block is also made of stone and completes the magnificent design of the Gerdab-e Sangi. During the rainy seasons like spring, the spring can produce 170 liters of water in just a second. It is one of the interesting characteristics of this historical attraction. The water flows from the well to the channels throughout the city and it also makes the weather around this structure very pleasant and fresh.
