Shushtar Historical Hydraulic System

Shushtar water structures complex in Iran is one of the spectacular and extraordinary attractions of Khuzestan province. This complex is known as the largest industrial complex before the industrial revolution, which is unique not only in Iran but also in the world. This amazing structure dates back to the Sassanid period.

The crossing of the Karun and Dez rivers in Shushtar city has led to the construction of a regular and huge irrigation system made of clay, mud, wood and zinc, which brings water to people's houses through the basement. They also cause the watering of agricultural lands and the use of mill wheels to prepare wheat flour. This structure consists of bridges, dams, waterfalls, canals and large tunnels that are very coordinated and regularly connected with each other and has the role of directing water. This beautiful and unique complex was created with the aim of making the most of water.

This interconnected complex with 13 historical works, part of it has been eroded and lost over the time, and only a part of it remains, has been registered  as Shushtar Historical Hydraulic System, on July 5, 2008, as the 10th world work in the UNESCO World Heritage List.
