Although Shanghai Tower is the 2nd tallest building in the world, its observation deck is the tallest. We bought tickets and went up to view the city. They took our photos and it can be printed with a high fee. We did not need so they printed our small photo in the Shanghai Tower photo. Up the observation desk we could see the Shanghai World Financial Tower, Jin Mao Tower and Pearl TV Tower, all are very short and tiny. With the 632 meter height, this is very eye catching tower, a not to miss attraction in Lujiazui.
