CN Tower
because it just is okay
I suspect you are thinking of the CN Tower. But the CN Tower is not the world's largest structure, never was, and doesn't even come close. It is tall, very tall, but quite thin. The CN Tower was (but is no longer) the world's tallest free-standing structure.
Canada's highest structure is the CN Tower in Toronto.
The CNN Tower, also known as the CN Tower, is primarily considered a shell structure due to its design and construction. Its iconic tall, slender shape relies on the strength of its reinforced concrete and steel, allowing it to withstand various forces, including wind and seismic activity. The tower's cylindrical form effectively distributes loads, making it efficient as a shell structure while also providing a distinctive aesthetic. Thus, while it has solid elements, it exemplifies the characteristics of a shell structure.

Direct quote from the Wikipedia article on the structure... "...Its name "CN" originally referred to Canadian National, t he railway company that built the tower..."
The CN Tower is considered a shell structure due to its lightweight, hollow design, which provides strength and stability while minimizing material usage. Its cylindrical shape efficiently distributes loads and resists wind forces, making it ideal for tall structures. The tower's exterior acts as a protective shell, contributing to its overall integrity and aesthetic appeal. This design allows it to reach impressive heights while maintaining a slender profile.
