Sivand Dam
The 772nd tallest dam in the world
Sivand Dam is a dam built in 2007 in Fars province, Iran. Named after the nearby town of Sivand located northwest of Shiraz, it was the center of worldwide concern because of the flooding it would cause in historical and archaeologically rich areas of Ancient Persia and possible harm it may cause to the nearby UNESCO World Heritage Sites of Persepolis and Pasargadae.
