CN Tower - Wikipedia, the free encyclopedia: "The CN Tower, located in Toronto, Ontario, Canada, is the world's tallest freestanding structure on land, standing 553.33 meters (1,815 ft 5 in) tall. It is considered the signature icon of the city, attracting more than two million international visitors annually.[1] Guinness World Records has listed the CN Tower as the world's tallest building since its completion in 1976. From a technical perspective, however, it is not considered a building by the Council on Tall Buildings and Urban Habitat, which ranks tall buildings."
