About this subject

The CN Tower is a communications and observation tower located in downtown Toronto, Ontario, Canada. Completed in 1976 after three years of construction, the structure reaches 553.3 meters in height, making it the world's tallest tower and the tallest freestanding structure on land for 32 years, until the Burj Khalifa was completed in 2010. Designed by architects John Andrews, Webb Zerafa, Menkes Housden, and engineer Roger Nicolet, the tower was built by the Canadian National Railway (CN) to solve radio and TV transmission problems caused by the city's skyscrapers.

The tower features several renowned attractions, such as the Glass Floor on level 113, which offers a view of the ground 342 meters below, and the EdgeWalk, an outdoor walk around the edge of the main observation deck at 356 meters, considered the highest full-circle walk in the world. The 360 revolving restaurant on level 114 completes the experience, providing a panoramic view of the city and Lake Ontario. The structure also houses the LookOut Level at 346 meters with unobstructed views.

Beyond its role as a tourist landmark, the CN Tower serves a vital communications function: its antennas transmit radio, TV, and data signals across the Greater Toronto Area. The original name was simply 'CN Tower', but after the privatization of the Canadian National Railway, the name was retained, though the tower is now owned by Canada Lands Company. The structure is recognized as one of the Seven Wonders of the Modern World by the American Society of Civil Engineers.

Interestingly, during strong winds, the top of the tower can sway up to 1.5 meters, and the design includes a damping system to minimize oscillations. The CN Tower has welcomed over 70 million visitors since its opening, making it one of Canada's most visited destinations.
