The CN Tower's Unseen Spaces: A Rare Glimpse at Canada's Engineering Heritage The CN Tower, a symbol of Toronto's skyline and Canadian engineering prowess, is marking its 50th anniversary with a grand celebration.
As part of the city's Doors Open Toronto event, the tower has opened up areas normally off limits to the public for rare access.
Behind the tower's gleaming exterior lies a complex network of mechanical systems, hidden passageways, and operational areas that are normally invisible to visitors.
