The 1976SummerOlympics, officially known as the Games of the XXI Olympiad, were held in 1976 in Montreal, Quebec, Canada.
The Olympic Stadium, a daring design of French architect Roger Taillibert, remains a lasting monument to the huge deficit, as it never had an effective retractable roof, and the tower was only completed after the Olympics.
Montreal 1976 pointed the way to the future in Olympic security, which was further increased for the 2002 Winter Olympics in Salt Lake City.
