Historic District of Old Quebec - Canada

Québec City is the only city in North America to have retained its colonial ramparts, bastions, gates and defence works. The urban combination formed by the Haute-Ville, located at the summit of a cape, with its churches, convents, the Citadel and the famous Château Frontenac, and the Basse-Ville, with its Place-Royale and centuries-old homes, is a splendid example of a fortified colonial town.
