Sangi Whirlpool of Lorestan – Sassanid-Era Water Technology

🌀 Water has always played a vital role in human life and has been an essential element throughout history. In ancient times, many innovations were used to store and transport water to different parts of a city. As you travel through various regions of Iran, you will come across water reservoirs (known as ab-anbars) that were historically used for water storage. The Stone Whirlpool in the city of Khorramabad is one such structure, built during the Sassanid era to collect spring water and distribute it to different parts of the city.

Locally known as "Gerdav-e Bardineh," the Stone Whirlpool is one of the historical monuments remaining from the Sassanid period in Khorramabad.


🌀 Why Did the Sassanids Design the Stone Whirlpool in a Circular Shape?

The Stone Whirlpool is circular in shape and was built around a spring using lime and gypsum. Its purpose was to manage the outflow of water from the spring and then channel it through canals to various parts of the ancient city of Shapurkhast. The spring of the Stone Whirlpool contains water almost throughout the entire year.

The structure has a diameter of 18 meters, an area of 256 square meters, a width of 3 meters, and a depth of 18 meters from the top to the bottom of the spring. The Stone Whirlpool includes a sluice gate measuring 90 × 160 centimeters to transfer water from the whirlpool into distribution canals.
