Canton Tower, at 610 meters counting the 156 meter antenna that sits atop the 454 meter tower proper (which is the consensus on how to measure the total height of a tower), is currently the world’s tallest tower, and given its unique construction, which facilitates “building high”, Canton Tower will likely remain the tallest tower for some time, unless someone comes up with a building design that is even more clever than that of Canton Tower (note that Canton Tower is the world’s tallest tower, not the world’s tallest building… there is a limit to the size of the base of an edifice that can qualify as a tower rather than as a building – to satisfy your curiosity, the world’s tallest building is the Burj Khalifa in Dubai, standing at 828 meters, including its spire).
