The Three Gorges Dam is the world’s largest dam, stretching 2.4 km (1.5 mi) across the Yangtze River, and standing 183 m (600 ft) tall.  Dr. Sun-Yat-sen, the great revolutionary leader and “father of modern China” first proposed the idea back in 1919.  The Three Gorges Dam is the world’s largest hydropower station and there has been heated international debate surrounding the project’s environmental impacts and resettlement difficulties, among many other issues.  It is by all accounts a modern marvel and usually the culminating destination of a cruise on the Yangtze River.
