Completed in 2008. It is a mixed-use skyscraper, consisting of offices, hotels, conference rooms, observation decks, and ground-floor shopping malls. Park Hyatt Shanghai is the tower's hotel component and it is now the third-highest hotel in the world after the Ritz-Carlton, Hong Kong.
The original design specified a circular aperture, 46 m in diameter, to reduce the stresses of wind pressure and to reference the Chinese mythological depiction of the sky as a circle.It also resembled a Chinese moon gate due to its circular form in Chinese architecture. However, this initial design began facing protests from some Chinese, including the mayor of Shanghai, Chen Liangyu, who considered it too similar to the rising sun design of the Japanese flag. The leading architect – Kohn Pedersen Fox - then suggested that a bridge be placed at the bottom of the aperture to make it less circular.
