Canton Tower

The Canton Tower (), formally Guangzhou TV Astronomical and Sightseeing Tower (), is a -tall multipurpose observation tower in the Haizhu District of Guangzhou (alternatively romanized as Canton). The tower was topped out in 2009 and it became operational on 29 September 2010 for the 2010 Asian Games. The tower briefly held the title of tallest tower in the world, replacing the CN Tower, before being surpassed by the Tokyo Skytree. It was the tallest structure in China prior to the topping out of the Shanghai Tower on 3 August 2013, and is now the second-tallest tower and the fifth-tallest freestanding structure in the world. Naming and etymology There had been a long discussion about the naming of the Canton Tower since the commencement of its construction in 2005 after the groundbreaking ceremony. In September 2020, at the request of the tower's investor, Guangzhou Daily launched a contest for naming proposals. The contest attracted over valid entries, among which "Haixin Tower" () was awarded the first prize. The name alluded to the city's historical setting as the start of the Maritime Silk Road and the tower's geographical proximity to Haixinsha Island. However, this name was considered obscure to people unfamiliar with the history of the city. Local residents continued to refer to the tower by various nicknames including "Slim Waist" (), "Twisted Firewood" (; a metaphor for "stubborn" in Cantonese) and "Yangdianfeng" (; homophone of "epilepsy" in colloquial Chinese). The Naming was reconsidered in 2010. After surveying a broad range of public opinions, "Canton Tower" was decided as the official English name and announced at the end of September 2010. The new English name, which alludes to the city's prosperous past, was considered the most identifying and least ambiguous among the multitude of proposals.
