Fort Lennox National Historic Site

Located in Saint-Paul-de-l'Île-aux-Noix, in the Montérégie region, Fort Lennox National Historic Site includes a fortification built on Île aux Noix, itself encircled by the Richelieu River.

A situation beyond our control has forced us to temporarily suspend access to the fortification buildings.
From June 15, 2024, until further notice, Parks Canada staff accompanies visitors to Île aux Noix and offers a guided outdoor tour of the buildings and fortification. This 45-minute tour will be offered free of charge. Please note that it is not possible to picnic on the island. Picnic tables are available on the pier near the boarding dock.
