Tang-e Ab Dam, Gerash

Tang-e Ab Dam is one of the historical and natural attractions of Fars Province. It lies southwest of the city of Gerash, in a gorge of the same name, on the slopes of Mount Siyah below the peak of Bon-e Moruk. This ancient dam dates back to the Sasanian era and was rebuilt during the Safavid period.

It was built of stone and sarooj (a traditional waterproof mortar), and a channel made of the same materials runs from the dam to a plain known as Dasht-e Bara, to irrigate the fields. Two sarooj reservoirs have also been built along this channel. The structure was added to Iran's National Heritage list in the summer of 1380 (2001).

To reach Tang-e Ab Dam, drive southwest from the city of Gerash. After about 2.5 kilometres on a paved road, you turn onto a 5.5-kilometre dirt road that leads to the dam site. The best time to visit is during Esfand and Farvardin (roughly late February to April), when the surrounding plains turn green and are covered in flowers. When visiting, please practise responsible nature tourism and keep the environment clean.
