China is a top producer of skyscrapers, and among the hundreds of these lofty architectural feats, the tallest can be found in Shanghai. The Shanghai Tower is yet unchallenged in its 632-meter height and 128-floor stack. Looking up to it are other notable towers in the city, including the Shanghai World Financial Center, the Oriental Pearl Tower and the Jin Mao Tower. Taken altogether, Shanghai's more than 80 towers create the city's amazing scape, not only from the ground but--thanks to aerial photography--also among the clouds.
