Fort Chambly National Historic Site
Roughly 30 kilometres southeast of Montreal, Fort Chambly rises proudly at the foot of the Richelieu River rapids. Built in 1711 to defend the colony, this stone fortification was preceded by three wooden forts.
Fort Lennox National Historic Site
Built on Île aux Noix between 1759 and 1760, Fort Lennox reopened its doors after major restoration work. This mythical site was at the heart of the French defence against the British invasion by the Richelieu River, and the ferry ride to get there is worth a visit.
