Artist Ai Weiwei was the consulted artist on this project. The official stadium used in the 2008, Beijing Olympics; nicknamed "Bird's nest" Originally to have a retractable top, that was stopped under the creative influence of Ai Weiwei who chose to then also hide the steel beams that cover the outside; there are 24 steel beams that weight 1,000 tons each. 17,000 workers and 290 Million US Dollars were the estimated cost of construction. At its height, it could hold a capacity of 90,000 that was during the olympic soccer gold match. I appreciate the colors, the lights, especially at night. I appreciate how quickly it was build (2003-2008).
