What will cities be like in the future? The Pavilion of Future at the World Expo in Shanghai has the answer. Through movies, books and sculptures, the exhibition reviews what people used to imagine cities would be like, and depicts what people today envision cities will be like in the future.

The pavilion was converted from the old building of the Nanshi Power Plant. The plant used to be a symbol of Shanghai's industrialization. Today, it has been turned into a green building to showcase urban progress and the future of cities.
