Shanghai—Lujiazui in particular—has numerous skyscrapers, making it the fifth city in the world with the most skyscrapers. Among the most prominent examples are the high Jin Mao Tower, the high Shanghai World Financial Center, and the high Shanghai Tower, which is the tallest building in China and the second tallest in the world. Completed in 2015, the tower takes the form of nine twisted sections stacked atop each other, totaling 128 floors. It is featured in its double-skin facade design, which eliminates the need for either layer to be opaqued for reflectivity as the double-layer structure has already reduced the heat absorption. The futuristic-looking Oriental Pearl Tower, at , is located nearby at the northern tip of Lujiazui. Skyscrapers outside of Lujiazui include the White Magnolia Plaza in Hongkou, the Shimao International Plaza in Huangpu, and the Shanghai Wheelock Square in Jing'an.
