'The Three Gorges Dam, Yangtze River, China' - One of the Engineering Wonders of the World.
Rising from the waters of the Yangtze River, the Three Gorges Dam stands more than 40 storeys high. It has a capacity of over 39,300,000,000 litres. The scale and scope of the project is stunning. The dam stretches for over 2km (1.25 miles), took tens of thousands of workers over a decade to build and cost more than $40bn (£25bn).
Designed to control the flooding of the mighty river, the dam produces vast amounts of electricity - the equivalent of 11 nuclear power stations. It is one of the most impressive feats of civil engineering anywhere in the world and stands as a symbol of China's progress over the last 20 years.
Unsurprisingly, the Communist Party has hailed the mega-project as a triumph. But the dam has come at an enormous environmental and human cost. More than a million people were forced to relocate when the dam created a lake 600km in length that submerged villages, towns and small cities.
