The Shushtar Historical Hydraulic System, located in the historic city of Shushtar in Khuzestan Province, is one of the most remarkable feats of ancient engineering in Iran. Dating back to the Sassanid era (3rd century CE), this extensive network of dams, canals, tunnels, bridges, and watermills was ingeniously designed to channel and control water from the Karun River, supporting agriculture, industry, and urban life.
Recognized as a UNESCO World Heritage Site in 2009, the system reflects centuries of innovation and sustainable urban planning. It highlights how Persian engineers skillfully combined technical knowledge with practical solutions to create a water management network that has endured for over 1,700 years.
Highlights of the Site
Gargar Bridge-Dam: The main diversion structure that channels water into Shushtar’s complex canal system.
Watermills and Factories: Some still operational today, these mills powered local industries, from grinding grain to irrigation.
