The H.R. MacMillan Space Centre, founded 1968, is an astronomy museum in Vanier Park, Vancouver, BC, Canada. The Space Centre is named for H.R. MacMillan, a British Columbia industrialist and philanthropist. The building was designed in the 1960s by architect Gerald Hamilton to house what was then called The Centennial Museum. The planetarium was added as part of a pre-construction re-design. The Space Centre originated as the H.R. MacMillan Planetarium until its re-branding in the 1990s when it expanded to include exhibit space into one of the wings of the building it shares with the Museum of Vancouver.
