Frequently asked questions
What is the CN Tower made of?
The CN Tower is built primarily from reinforced concrete, with a steel antenna mast at the top. The concrete shaft accounts for the majority of its roughly 117,910-metric-ton weight.
How tall is the CN Tower?
The CN Tower stands about 553 meters tall and was the world's tallest free-standing structure from 1976 until 2007. It remains one of the tallest towers in the world.
Why is the CN Tower so heavy?
Its great height required a massive reinforced concrete shaft and a deep foundation to remain stable as a free-standing structure. This concrete-heavy design gives it a large total weight.
