History:
The stone whirlpool dates back to the 3rd century AD and the period of the Sassanid dynasty of Shapur I.
The purpose of building this structure was to store and transfer spring water to different areas of the city and Falak Alaflak Castle.
At that time, Sasanian engineers skillfully and carefully built a channel inside the thick walls of the stone whirlpool to direct the water to the surface of the earth.
The stone whirlpool has been renovated throughout history. The last restoration was done in 1379.
