In the early 19th century this was just a clear space surrounded by a picket fence and poplar trees. The French began building ramparts along the city's cliffs as early as 1690 to protect themselves from British invaders. However, the colonists had trouble convincing the French government to take the threat of invasion seriously, and when the British invaded in 1759 the walls were still incomplete. The British, despite attacks by the Americans during the American Revolution
and the War of 1812, took a century to finish them—and they never saw armed conflict. From June to early October, the park is the starting point for walking the city's 5 km (3 miles) of walls. There are two guided tours (adults C$9.80); one starts at the interpretation center and the other begins at Terrasse Dufferin.
