Three Gores Dam
The world's largest hydroelectric plant is in the course of the Yangtze River near the city of Sandoupin. To build this project, the Chinese government had to relocate 1.24 million people because 13 cities, 140 towns and 1350 villages, were partially or fully flooded. The construction began on December 15, 1993, and it officially ended on 30 October 2010.
