World Financial Center, Shanghai
As of the end of 2008, the SWFC is China's tallest building and the world's second tallest completed building (after Taipei 101), with a height of 492 metres. It has a trademark trapezoid hole at its top. Visit one of its observation decks on floors 94, 97 or 100 (the 100th floor one is the world's highest, with a vertigo-inducing glass floor), for stupendous views of Shanghai, assuming clouds don't obscure your views. Entry to the 100th floor observation deck costs RMB150 for adults and RMB75 for children (2009 prices). The top floors of the SWFC house the Park Hyatt, with the world's highest hotel rooms and bar. The lower floors house shops and restaurants, while most of the rest of the building are occupied by offices.
The Shanghai World Financial Centre Building in Pudong is the highest building in China and the second tallest in the world at a height of 492m (1,614ft). It opened on the 28th October 2008 and the Observation Deck at the highest vantage point at 474m (1,555ft) opened a couple of days later. Unfortunately I visited Shanghai a few months before it opened in May 2008 when it was still being constructed as you can see by one of the photos I took from the neighbouring Jin Mao Tower.
