This city, which dates back to 1608 and is the capital of the province of Quebec, is very picturesque and charming. It also boasts a wonderful old town — Old Quebec — where you can walk cobblestone streets past well-preserved 17th- and 18th-century buildings. Old Quebec is the only walled city north of Mexico. Quebec City is also home to the Citadelle of Quebec, which is an active fort and museum. The Citadelle is also the largest British fortress ever built in North America.
