Quebec City is a charming city in the province of Quebec with strong European roots. Narrow, winding streets, old stone homes and churches, ramparts and cannons, copper roofs and Gallic architecture all bring to mind the Old World. The Citadel of Quebec and city walls make up the largest fortifications still in use in North America. The only walled city in the Western Hemisphere north of Mexico, Vieux Quebec is a UNESCO World Heritage Site.
