Centennial Planetarium

Advised by the director of the architecture department at the University of British Columbia, Henry Elder, the three finalists were McMillan Long, Gordon Atkins, and Bill Boucock.

Built on a site north of Mewata Armouries overlooking the Bow River, the Planetarium is constructed of raw concrete and features non-orthogonal design.

From 1971 to 1985, the Planetarium also housed the collection of aircraft, aero engines, and associated reference library that became the basis of the Hangar Flight Museum.

On 27 June 2011, the Calgary Science Centre ceased operations at the planetarium before moving to their new location in the Nose Creek valley, which opened in October of that same year.
