The Royal Ontario Museum (ROM) is a museum of art, world culture and natural history in Toronto, Ontario, Canada. It is one of the largest museums in North America and the largest in Canada. It attracts more than one million visitors every year, making it the most-visited museum in Canada. The 74,000 square metres (800,000 sq ft) museum building is located north of Queen's Park, in the University of Toronto district, with its main entrance on Bloor Street West. Museum subway station is named after it and, since a 2008 renovation, is decorated to resemble the ROM's collection at the platform level; Museum station's northwestern entrance directly serves the museum.
Established on April 16, 1912, and opened on March 19, 1914, the ROM has maintained close relations with the University of Toronto throughout its history, often sharing expertise and resources. It was under direct control and management of the University of Toronto until 1968, when it became an independent Crown agency of the Government of Ontario. It is Canada's largest field-research institution, with research and conservation activities worldwide.
