Yingdong Natatorium

　　    Situated in the garden-like National Olympic Sports Center, Yingdong Natatorium was constructed in 1986 for the 11th Asian Games. The natatorium covers a construction area of 38,000 square meters and can accommodate 6,000 spectators. It features a unique architectural style, advanced equipment, and comprehensive auxiliary facilities. The environment here is comfortable, and the water treatment system is state-of-the-art. The water quality is disinfected using chlorine, ozone, and other methods, and it undergoes multi-level filtration using natural quartz sea sand. The water quality meets international professional competition standards.

　　    Yingdong Natatorium served as the competition venue for water polo and the swimming segment of the modern pentathlon during the 2008 Beijing Olympics. Named “Yingdong” after the late Hong Kong businessman (who passed away in 2006), the natatorium was donated with HK$100 million by him for the construction of the Athletes’ Village when Beijing successfully bid to host the 1990 Asian Games. At that time, it was the largest natatorium in Asia. In addition, the natatorium also hosted the swimming events of the 2001 World University Games.

　　    To this day, the natatorium covers a construction area of 43,020 square meters and includes four pools: a standard competition pool, a training pool, a diving pool, and a warm-up pool. Due to its long history and status as one of the Beijing Olympic venues, the Beijing Olympic Committee began renovating the natatorium in December 2005, with the target completion date around September 2007.
