Quebec City was declared a World Heritage Site by UNESCO in 1985, and is the only remaining fortified city north of Mexico, .
Quebec City is not lacking in significant pieces of secular architecture. It has hundreds of surviving heritage homes which have been built in the particular style of New France. This style is an adaptation to the colder climes of Quebec of ancient 17th and 18th century house forms of Normandy and other traditional lands of the North of France.
