Olympic Park Observation Tower, Beijing, China designed by Shi Yingfang, Li Lei and Wen Yaling, height 243m. Construction began in 2008, to coincide with that year's Summer Olympics and completed/opened in 2014. It is used strictly for observation; there is no provision for offices or apartments. 258 metres (846 ft) in height, its design, with 4 smaller circular floors at different heights and positions below a larger top floor, is meant to echo the Olympic rings.
