Beijing digs new depth in Olympic legacy

The newly updated corridor on the roof of Beijing's iconic "Bird's Nest" has been open to the public which enables tourists to overlook the Chinese capital on the highest point of the 2008 Olympics main stadium.

The corridor, extended to 1,000 metres from some 200 metres, is made of stainless steel and runs all across the roof from south to north with a stopping point at the

west end of the roof where is the highest point of the stadium at 69 metres.

On the roof, one can stand on the huge steel beams which are woven into a gigantic nest-like structure. It earns the stadium the nickname "Bird's Nest", and offers a

stunning view that includes Beijing Olympics aquatic center "Water Cube", Linglong tower for broadcasting during the Games, the dragon-shaped river as well as various highrises.

As one of the Beijing Olympics' most famous legacies, Bird's Nest has become an important tourist destination in Beijing, hosts international soccer matches

and concerts.
