The Hangzhou Olympic Center's main stadium, aquatics center, and integrated training center recently passed their final acceptance inspection, local media outlets reported.

The main stadium and aquatics center resemble the wings of a butterfly. The two facilities started construction on Jan 26, 2018 and cover a total area of 397,000 square meters. The venues will host basketball, swimming, diving, and synchronized swimming events during the Games. [Photo/zjol.com.cn]

The 184,500-sq m integrated training center will host basketball, volleyball, handball, fencing, and taekwondo events during the 2022 Games. The venue resembles a cong, a jade ritual vessel in ancient China with holes and rectangular sides. The cong is a representative cultural relic unearthed in Hangzhou that bears the remnants of the 5,000-year-old Liangzhu civilization, which was inscribed on the UNESCO World Heritage List on July 6, 2019.
