The primary venue of the 2008 Beijing Olympic Games, Olympic Green houses Beijing’s sports grounds, including the National Stadium, National Aquatics Center and National Indoor Stadium and some other affiliated facilities, such as the Olympic Village and News Center. Both the opening and closing ceremonies of the Olympic games, along with track-and-field competitions, menís football final matches and other competitions, took place at the 91,000-seat National Stadium. Because of its unique design and interwoven structure, the stadium is also known as ‘Bird’s Nest’.
At the games, swimming, diving, figure swimming, water polo events all took place at the National Aquatics Center which accommodates 17,000 people. The building’s exterior was designed to resemble large water molecules which create an effect of flowing water when lit, hence its nickname “Water Cube”. After the Olympic Games, the park was transformed into a public venue for sports competitions, exhibitions, meetings, cultural recreations and entertainment activities.
