The Cathedral-minor basilica of Notre-Dame de Québec (Our Lady of Quebec City), located at 20, rue de Buade, Quebec City, Quebec, is the primate church of Canada and seat of the Roman Catholic Archdiocese of Quebec, the oldest see in the New World north of Mexico.
It is also the parish church of the oldest parish in North America, and the first church in North America to be elevated to the rank of minor basilica by Pope Pius IX in 1874. It is a National Historic Site of Canada, and located within the UNESCO World Heritage Site of Historic District of Old Québec.
Old Québec (French: Vieux-Québec) is a historic neighbourhood of Quebec City, the capital of the province of Quebec in Canada. Comprising the Upper Town (French: Haute-Ville) and Lower Town (French: Basse-Ville), the area is a UNESCO World Heritage Site. Administratively, Old Quebec is part of the Vieux-Québec–Cap-Blanc–colline Parlementaire district in the borough of La Cité-Limoilou.
The area is sometimes referred to as the Latin Quarter (French: Quartier latin), but this title refers more to area around the Séminaire de Québec, the original site of Laval University.
