杭州奥体中心体育场

Hangzhou Olympic Sports Center Stadium stands at 3 Feihong Road, Binjiang District, Hangzhou, on the south bank of the Qiantang River in the Olympic Sports Expo City. Known as the Big Lotus, it was the main venue for the opening and closing ceremonies of the 19th Asian Games and the 4th Asian Para Games, and it marks Hangzhou's shift from a West Lake-centred city to one oriented to the Qiantang. The stadium covers 430 mu, rises 59.4 m and has 216,000 sqm of gross floor area over six levels above ground and two below, with 80,800 fixed seats, making it the second-largest stadium in China after the Bird's Nest. The ground floor holds competition rooms, the second level forms a ring platform linked to the neighbouring Small Lotus tennis centre, the fifth level contains 86 boxes, and there is a 3,000 sqm warm-up hall with a 60 m track; the basement houses the Hangzhou Asian Games Museum and intangible heritage displays. The architecture is composed of 28 large and 27 small petals, with gaps between them like traditional Chinese window frames. The facade uses perforated aluminium-manganese panels with 5 mm holes for daylight and shading, and the steel structure weighs about 28,000 tonnes, some 14,000 tonnes less than the Bird's Nest. Seats shade from purple in the east to blue in the west, a motif meaning 'purple air coming from the east'. Metro Lines 6 and 7 stop at Olympic Sports Center, and the venue has been fully open to the public since 2024. A raised platform links the stadium with the Small Lotus tennis centre, the Hangzhou Asian Games Museum and the Linheli retail street, forming a walkable venue cluster.
