The Mills of Shushtar
In 1992 Michael Harverson visited Iran to look for watermills. One of the most memorable sites he visited was Shushtar in the Khuzestan province. In this region are to be found the largest rivers in Iran, flowing from the Zagros mountains to the Persian Gulf. On the river Karun is the ancient bridge of Valerian, said to have been built by Roman soldiers captured in battle by the Sassanid ruler Shapur I at the Battle of Edessa in 260 AD.
