Ramparts of Quebec City

Located in Canada, the Ramparts of Quebec City are the only remaining fortified city walls in North America north of Mexico. The British began refortifying the existing walls, after they took Quebec City from the French in the Battle of the Plains of Abraham in 1759.

The wall surrounds most of Old Quebec, which was declared a World Heritage site by UNESCO in 1985. The fortifications were designated a National Historic Site of Canada in 1948.
