High Quality Content by WIKIPEDIA articles! Rideau Hall is, since 1867, the official residence of the Governor General of Canada, as well as that in Ottawa of the Canadian monarch. It stands in the Canadian capital on a 0.36 km2 (88 acre) estate at 1 Sussex Drive, with the main building consisting of 170 rooms across 9,500 m2 (102,000 ft2), and 24 outbuildings around the grounds. While the equivalent building in many countries has a prominent, central place in the national capital (Buckingham Palace, the White House, and the Royal Palace of the Netherlands, for example), Rideau Hall's site is relatively unobtrusive within Ottawa, giving it more the character of a private home.
