New Delhi: The CN Tower, located in Toronto, the heart of Canada, was once the world’s tallest man-made structure. Built in 1976, it stands at 553.33 meters (1,815 feet). At the time, it was the first concrete structure to reach this height. For nearly 34 years (1976–2010), the CN Tower held the record for the world’s tallest free-standing structure, until it was surpassed by the Burj Khalifa (828 m). However, it is not included among the world’s tallest buildings.

Situated in the heart of the city, it appears to pierce the skyline. It attracts over two million tourists each year, and almost every tourist stops to admire it.
