The Shanghai World Financial Center (SWFC; Chinese: 上海环球金融中心; pinyin: Shànghǎi Huánqiú Jīnróng Zhōngxīn, Shanghainese: Zånhae Guejieu Cinyon Tsonsin) is a supertall skyscraper located in the Pudong district of Shanghai. It was designed by Kohn Pedersen Fox and developed by the Mori Building Company, with Leslie E. Robertson Associates as its structural engineer and China State Construction Engineering Corp and Shanghai Construction (Group) General Co. as its main contractor. It is a mixed-use skyscraper, consisting of offices, hotels, conference rooms, and a ground-floor shopping mall.
On 14 September 2007, the skyscraper was topped out at 492 meters (1,614.2 ft), making it the 2nd tallest building in the world on completion (the tallest at the time being Taipei 101), the tallest building in the world by roof height only, and the tallest in mainland China. The SWFC opened to the public on 28 August 2008, with its (since closed) observation deck opening on 30 August. The observation deck offered views from 474 m (1,555 ft) above ground level.
