Which attraction is considered one of the tallest freestanding structures in the world?

The CN Tower is recognized as one of the tallest freestanding structures in the world due to its remarkable height of 553.3 meters (1,815 feet). Located in Toronto, Canada, it held the title of the tallest freestanding structure from its completion in 1976 until 2010 when it was surpassed by the Burj Khalifa in Dubai, which is a different category as it is a building rather than merely a freestanding structure.

Freestanding structures are typically not supported by other buildings, which distinguishes them from architectural skyscrapers. The CN Tower serves as a communication and observation tower, showcasing its design specifically for height and functionality without being categorized as a traditional high-rise building. This highlights its significance in architectural feats as well as its role in skyline aesthetics and tourism in Toronto.
