Bird's Nest - The Beijing 2008 Olympic Stadium

Design:

In 2002, Government officials engaged architects worldwide in a design competition. Pritzker Prize-winning architects Herzog & de Meuron collaborated with ArupSport and China Architecture Design & Research Group to win the competition. Contemporary Chinese artist, Ai Weiwei, is the Artistic Consultant for design. The ground was broken on Christmas Eve December 2003, and construction started in March 2004, but was halted by the high construction cost in August 2004 and continued again. In January 2008, concerns about construction working conditions arose when it was revealed that at least 10 workers had died during the stadium's construction. Controversy also surrounded the alleged forced evictions of many residents so the construction could go ahead.
