Thick stone walls stretch along 5 km (3 miles), connected by four gates—St-Jean, St-Louis, Kent, and the more modern Prescott—and adjoined by forts, bastions, and even a citadel. With such a special and unique landmark, it's not difficult to understand why the Historic District of Old Québec is a UNESCO World Heritage site. These nearly intact ramparts, virtually the only ones of their kind in North America, recall the complex history of the French and British regimes in Québec City. French colonists began building ramparts along the city's cliffs as early as 1690 to protect themselves from the British, but they had trouble convincing the French government to take the threat of invasion seriously. And when the British did invade in 1759, the walls were unsurprisingly still incomplete. The British, despite attacks by the Americans during the American Revolution and the War of 1812, took over a century to finish them—and they never saw armed conflict.
From June to September, Parks Canada offers two distinct guided tours of Québec City's fortifications, each led by a knowledgeable history guide. The first is a two-hour tour, departing from the Frontenac Kiosk on Dufferin Terrace. This experience leads participants along the fortification walls and into a soldier's casemate—an area exclusively accessible on this tour—while sharing fascinating historical tidbits about the city. The second tour is entirely within Artillery Park, one of the oldest military compounds in the Americas, dating back to 1712. This experience focuses on the social and architectural heritage of the ramparts building, which has housed French, British, and Canadian soldiers throughout history.
