The CN
Tower is a communications and observation tower in Downtown Toronto, Ontario,
Canada.
Standing 553.3 metres (1,815 ft) tall, construction of the the world's tallest free-standing structure
and world's tallest tower was finished in 1976. It held both records for 34 years. It remains the
tallest free-standing structure in the North America, attracting more than two million international
visitors annually. Its name "CN" originally referred to Canadian National, the
railway company that built the tower. Since local residents wished to retain the name CN Tower, the
abbreviation is now said to expand to Canada's National Tower, rather than the original Canadian
National Tower. In 1995, the CN Tower was declared one of the modern Seven Wonders of the World
by the American Society of Civil Engineers.
It also belongs to the World Federation of
Great Towers, where it holds second-place ranking. |
