Quebec City: The Fortifications and Citadel
Only two cities in North America have preserved their original fortifications. One is Campeche, Mexico, which we visited while living in the Yucatán. And now that we've been to Quebec City, our exploration of North America's Fortified Cities is complete. We went on a walk around Old Quebec's ancient walls, ending up at the Citadel, which was built by the British between 1820 and 1850.
