The Beijing National Aquatics Center (simplified Chinese: 北京国家游泳中心; traditional Chinese: 北京國家游泳中心), also officially known as the National Aquatics Center, and colloquially known as the Water Cube (Chinese: 水立方), is an aquatics center that was built alongside Beijing National Stadium in the Olympic Green for the swimming competitions of the 2008 Summer Olympics. Despite its nickname, the building is not an actual cube, but a cuboid (a rectangular box).
