Lightning CN Tower- 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 at the time. 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.
