Description: This is the new world's largest building. The new Terminal 3 at the airport in Beijing is twice the size of the Pentagon.
Adorned in the colors of imperial China, with a roof that evokes the scales of a dragon, the massive glass- and steel-sheathed structure, designed by the British architect Norman Foster, cost $3.8 billion and can handle more than 50 million passengers a year.
The developers call it the "most advanced airport building in the world," and say it was completed in less than four years, a timetable some believed impossible. It opened in late February 2008.
