Dominion Observatory, Astronomical observatory at Central Experimental Farm, Ottawa, Canada
The Dominion Observatory features a 15-inch refracting telescope installed within a Romanesque Revival architecture building constructed in 1905.
The facility operated from 1902 to 1970 as Canada's primary astronomical research center, providing national timekeeping services and coordinate measurements for mapping.
Scientists at the observatory conducted extensive star position measurements, recording 28,000 astronomical observations between 1911 and 1923 for national mapping purposes.
The observatory building now serves as offices for Natural Resources Canada, while its original telescope resides at the Canada Science and Technology Museum.
The observatory managed a network of 700 synchronized clocks throughout Ottawa's federal buildings by 1930, establishing the national time standard.
