Bird's Nest

The Bird's Nest is the nickname given to the Beijing National Stadium. It is considered one of the most unique designs in Olympic history. There is no distinction between the decorative and the structural portions of stadium.

The outside consists of enormous beams that resemble silver twigs making the stadium look like a huge bird's nest. Although, the design was inspired by the study of Chinese ceramics.

The 24 main columns weigh between 500 and 800 tons each. It is the world's largest steel structure, containing 110, 000 tons of steel.

The stadium was host to the Opening and Closing Ceremonies as well as Track and Field events and Soccer finals.
