Bird's Nest - Beijing National Stadium

Beijing National Stadium, nicknamed "Bird's Nest" due to its architecture, hosted the 2008 Summer Olympics. Completed in March 2008, it was built from a lattice of interwoven metal that seems to be arranged in a random pattern.


The stadium can seat as many as 91,000 spectators during the Olympics. The capacity will then be reduced to 80,000 after the Olympics. The stadium is 330 meters (1,082 ft) long by 220 meters (721 ft) wide, and is 69.2 meters (227 ft) tall. It uses 258,000 square meters (2,777,112 square feet) of space and has a usable area of 204,000 square meters (2,195,856 square feet). It was built with 36 km of unwrapped steel, with a combined weight of 45,000 tonnes. The stadium will cost up to 423 million USD.
