 | | The CN Tower, located in Toronto, Ontario, Canada, is the world's tallest freestanding structure on land, standing 553.33 metres (1,815 ft 5 in) tall. |
 | | Concrete was poured continuously by a team of 1,537 people until February 22, 1974, during which it had already become the tallest structure in Canada, surpassing the recently built Superstack which was built using similar methods. |
 | | There are also many guyed towers taller than the CN Tower, the current tallest being the KVLY-TV tower in North Dakota at 628 metres (2,063 ft) tall (see List of masts), but these are guy-wire supported structures (which are essentially very tall frameworks that support TV lines) and hence, are not classified as free-standing. |
