The Olympic Green is an Olympic Park in Beijing, China constructed for the 2008 Summer Olympics. The Beijing National Stadium ("Bird's Nest") is the centerpiece of this project. It hosted the opening and closing ceremonies, athletics, and football finals of the Games. The stadium has room for 80,000 spectators. The stadium cost US$423 million. Beijing National Stadium was designed by a consortium of Herzog & de Meuron Architekten AG, Arup Sports, and China Architectural Design and Research Group. The design, which originated from the study of Chinese ceramics, implemented steel beams in order to hide supports for the retractable roof; giving the stadium the appearance of a "Bird's Nest". The designers didn't do any redundant disposals to the look of the stadium. They just exposed the steel structures entirely and let them become the most natural appearance. The form of the stadium looks like a big nest which embraces and nurses human beings. Also it looks rather like a cradle bearing human beings' hope of the future. Dubbed the Bird’s Nest, the structure takes on the appearance of a nest as interwoven structural elements of the facade camouflage the structure underneath. The Bird’s Nest is supposed to gather roughly 70% of the water needed to run the facility. Also, there’s a movie coming out about the building. Since October, 2008, after the Olympics ended, the National Stadium has been opened as a tourist attraction. Now, it's the center of international or domestic sports competition and recreation activities. A beautifully crafted couple, the Water Cube (Beijing National Aquatics Center) floats bright, light, colourful, and pretty while the Birds Nest stands handsome, solid and strong. In the evenings they are glamorized in special LED designer lights is very sensational.
