Olympic Sports Centre (Beijing)
The Olympic Sports Center Stadium (simplified Chinese: 奥体中心体育场; traditional Chinese: 奧體中心體育場; pinyin: Àotǐ Zhōngxīn Tǐyùchǎng) is a multipurpose stadium in Beijing, China. It is currently used mostly for soccer matches. It was constructed in 1986 for the 1990 Asian Games. The complex contains the main stadium, an indoor arena, a hockey field, and a natatorium.
It was renovated to host the 2008 Summer Olympics, where it hosted soccer matches and the running and riding parts of the modern pentathlon events. For the riding discipline, the soccer field at the core of the venue has been turned into a high-standard temporary equestrian field. The renovation also added four pavilion-styled rotating rampways around the stadium.
The stadium has a floor space of 34,975 square meters, which exceeds the original building area of 20,000 square meters. Its capacity has doubled after the renovation, from about 18,000 to 36,228.
