An international symbol of Montréal, the Olympic Stadium — and its Tower, the world's tallest inclined tower — was designed by French architect, Roger Taillibert, and built in the 1970s as the main venue for the 1976 Summer Olympics. It is known by locals as "The Big O", a nickname that references both the Olympics and the circular shape of its roof. Its Esplanade, an urban park made up of nine platforms, also offers a breathtaking view of the Stadium and the Tower. A visit to the Olympic Stadium not only allows you to remember important events, but to discover that this witness to the history of the city still vibrates with true vitality. Its architectural, historical and patrimonial value is undeniable. Guides are happy to accompany visitors inside this bold and complex architectural masterpiece and to share both the technical details of its construction and anecdotes gleaned over the years and events.
