Beijing’s National Centre for the Performing Arts, and commonly described as "The Giant Egg", is an arts center containing an opera house, concert hall, and drama theatre. The center has underwater corridors, an artificial lake, and green space. It is believed to be the deepest architecture in Beijing with the deepest point being over 106 feet, equivalent to the height of a 10-floor building.
It was designed by French architect Paul Andreu and after 6 years of construction opened in July 2007.
The spectacular oval-shaped structure is an ingenious material integration of over 18,000 titanium plates and over 1,000 sheets of ultra-white glass, which creates a vivid visual effect as if the curtain is drawn apart slowly before your eyes.
"The Bird's Nest" is the nickname for Beijing's National Stadium, a joint design by Herzog & de Meuron and Ai Weiwei, completed before the 2008 Olympics.
