Dominion Astrophysical Observatory

The Dominion Astrophysical Observatory, located on Observatory Hill, in Saanich, British Columbia, was completed in 1918 by the Canadian government. The Dominion Architect responsible for the building was Edgar Lewis Horwood. The main instrument is the 72 inch aperture Plaskett telescope, proposed and designed by John S. Plaskett in 1910 with the support of the International Union for Cooperation in Solar Research.

The observatory has been designated a National Historic Site of Canada as it is a world-renowned facility where many discoveries about the nature of the Milky Way were made, and it was one of the world’s main astrophysical research centres until the 1960s.
