Beijing National Aquatics Centre in the context of Olympic Green

The 2022 Winter Olympics, officially called the XXIV Olympic Winter Games (Chinese: 第二十四届冬季奥林匹克运动会; pinyin: Dì Èrshísì Jiè Dōngjì Àolínpǐkè Yùndònghuì) and commonly known as Beijing 2022 (北京2022), were an international winter multi-sport event held from 4 to 20 February 2022 in Beijing, China, and surrounding areas with competition in selected events beginning 2 February 2022. It was the 24th edition of the Winter Olympic Games. These were the final winter games to take place under the IOC presidency of Thomas Bach.

Beijing was selected as the host city on 31 July 2015 during the 128th IOC Session in Kuala Lumpur, Malaysia, marking its second time hosting the Olympics and the last of three consecutive Games held in East Asia, following the 2018 Winter Olympics in Pyeongchang County, South Korea, and the 2020 Summer Olympics in Tokyo, Japan. Having previously hosted the 2008 Summer Olympics, Beijing became the first city to have hosted both the Summer and Winter Olympics. The venues for the Games were concentrated around Beijing, its suburb Yanqing District, and Zhangjiakou, with some events (including the ceremonies and curling) repurposing venues originally built for Beijing 2008 (such as Beijing National Stadium and the Beijing National Aquatics Centre).

Diving competitions at the Beijing 2008 Summer Olympics were held from August 10 to August 23, at the Beijing National Aquatics Centre.

The swimming competitions at the 2008 Summer Olympics took place from 9 to 17 August 2008 at the Beijing National Aquatics Centre. The newly introduced open water marathon events (10 km) were held on 20 and 21 August 2008 at Shunyi Olympic Rowing-Canoeing Park.

Swimming featured 34 events (17 male, 17 female), including two 10 km open-water marathons. The remaining 32 were contested in a 50 m long course pool within the Olympic Park.
