Lieu historique national de Coteau-du-Lac
Located nearby canal de Soulange, this historic site features Canada’s first lock canal and the remains of a fort. You can also see a blockhouse, military building erected in 1813, as the fort, to protect Canada (then a British colony) from possible US attacks. The channel, abandoned since the inauguration of the first Beauharnois Canal, can now be visited, both feet dry!

Construction of the Coteau-du-Lac canal began in the summer of 1779. Built by soldiers using rudimentary tools and techniques, this channel (100 m long and 2.5 m wide) was completed in 1781. It includes 3 locks, each 12 m long, 1.8 m wide and a draught of about 80 cm. It allows to bypass a drop of about 2 m between downstream and upstream of the rapid.
