The Citadelle of Quebec is a military installation and official residence of both the Monarch of Canada and the Governor General of Canada located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City, Quebec, Canada. It was first used as a royal necropolis by Thutmosis I, although it was his predecessor, Amenhotep I, who was considered as the patron-god of the valley by the actual builders of the tombs.
