The Cathedral-Basilica of Notre-Dame de Québec ("Our Lady of Quebec City"), located at 16, rue de Buade, Quebec City, Quebec, is the primatial church of the Roman Catholic Archdiocese of Quebec. It is the oldest church in Canada and was the first church in Canada to be elevated to the rank of minor basilica, by Pope Pius IX in 1874. Four governors of New France and the bishops of Quebec are buried in the crypt, including François de Laval, Quebec's first bishop.
The church is a National Historic Site of Canada, and located within the UNESCO World Heritage Site of Historic District of Old Québec.
The cathedral was designated as a national historic site of Canada in 1989 because "...of its long and close associations with the history of New France; its influence on subsequent ecclesiastical architecture and interior decoration in Québec."
