Oak Hall is a 37-room, three-story Tudor-style stone mansion that was built in the late 1920s for mining tycoon Harry Oakes (1874–1943). It is located in Niagara Falls, Ontario, approximately 1/4 mile southwest of the Canadian Horseshoe Falls. In 1959, Oak Hall was bought by the Niagara Parks Commission and opened to the public in 1964. The estate's original 9-hole golf course was turned into a public course in 1966. The mansion has housed the offices of the Niagara Parks Commission since 1982, and several historic rooms are still open for public viewing.
