About This Place
The David Dunlap Observatory in Richmond Hill, Ontario, is Canada's largest optical telescope and a National Historic Site. Once home to the country's primary astronomical research programme, the observatory has been transformed into a public heritage and educational attraction. Visitors can tour the historic 1935 main dome, gaze through the 74-inch telescope (one of the world's largest when built), and learn about Canada's rich history of astronomical discovery through guided experiences.
