The Canton Tower, or Guangzhou Tower (simplified Chinese: 广州塔; traditional Chinese: 廣州塔), officially the 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, Guangdong, China. The tower was finished in 2009 and it was first turned on 29 September 2010 for the 2010 Asian Games.
The tower held the title of tallest tower in the world, replacing the CN Tower. It was then passed by the Tokyo Skytree. It was the tallest structure in China before the Shanghai Tower was completed on 3 August 2013. It is now the second tallest tower in China and the fifth-tallest freestanding structure in the world.
