How was the cn tower designed?

The CN Tower was designed by the architectural firm WZMH Architects, with engineer John Andrews leading the project. Construction began in 1973, and the design aimed to create a symbol of Toronto while incorporating advanced engineering techniques to withstand wind and seismic forces. The tower's distinctive shape, featuring a central core and a wide base tapering to a narrow top, was both functional and aesthetic, allowing for observation decks and communication facilities. Completed in 1976, it became one of the tallest freestanding structures in the world.
