The Canton Tower, or Guangzhou Tower (simplified Chinese: 广州塔; traditional Chinese: 廣州塔), formally Guangzhou TV Astronomical and Sightseeing Tower (Chinese: 广州电视台天文及观光塔), is a 595.7 metres (1,954 ft) tall multi-purpose observation tower in the Haizhu District of Guangzhou (historically known as Canton or Kwangchow), Guangdong, China.[4][12][13] The tower was topped out in 2009 and it became operational on 29 September 2010 for the 2010 Asian Games.[14] The tower briefly held the title of tallest tower in the world, replacing the CN Tower, before being surpassed by the Tokyo Skytree.[15] It was the tallest structure in China prior to the topping out of Shanghai Tower on 3 August 2013. It is now the second tallest tower and the fifth-tallest freestanding structure in the world.
