Fort Chambly

Fort Chambly National Historic Site on the Richelieu River in Québec is a formidable square-shaped stone fortress built between 1709 and 1711 to protect New France from British invasion. The fourth fort constructed on this strategic location, it features four prominent corner bastions, high curtain walls, and a central courtyard surrounded by a large waterside park. Originally established in 1665 to control invasion routes and support French troops against the Iroquois, the fortress changed hands during the American invasion of 1775 and played crucial roles in the War of 1812 and the 1837-1838 rebellions. Designated a national historic site in 1920, Fort Chambly represents European classical military architecture adapted to North American defense needs.
