The CN Tower is a communications and observation tower in Downtown Toronto, Ontario, Canada. Standing 553.33 metres (1,815.4 ft) tall, it was completed in 1976, becoming the world's tallest free-standing structure and world's tallest tower. It held both records for 34 years until the completion of the Burj Khalifa and Canton Tower. It remains the tallest free-standing structure in the Western Hemisphere, a signature icon of Toronto's skyline, and a symbol of Canada, attracting more than two million international visitors annually.
