Tallest inclined structure

What to remember

The Leaning Tower of Pisa tilts by less than 4°. Montreal Tower leans at 45°. Designed by architect Roger Taillibert, it is part of Montreal's Olympic Stadium and Olympic Park, and at 175 m it is the tallest inclined structure.

Its height is sometimes given as 165 m, and its date as 1976. Planned for the 1976 Summer Olympics, the tower only reached its final height and officially opened in 1987. It has a clear job: the cables that open the stadium's retractable roof hang from it.

An inclined elevator runs up to its observatory, which presents the history of the stadium and of the Olympics. The stadium itself has 56,000 seats, expandable to 65,000, and was home to the Montreal Expos baseball team from 1977 to 2004.
