In addition to Place Ville Marie, the Queen Elizabeth Hotel, and the CN Headquarters, Montreal became home to one of the largest commercial retail/office developments in the world when Place Bonaventure was built above part of the Montreal Central Station terminal trackage. Although the site was a few blocks northeast of the former location of Bonaventure Station, the name was chosen to commemorate it. This development was built between 1966-1967, in advance of Expo 67. The newly commissioned Dow Planetarium was built on the actual site of the former Bonaventure Station.
