Fort Saint-Jean was originally built in 1665, on the western bank of the Richelieu River by soldiers of the régiment de Carignan-Salières and was rebuilt a number of times.
This is a plan of the fort as it was during the 1750s, consisting of palisades with four large bastions.
In 1760, toward the end of the French and Indian War, The French surrendered fort to the British.
During the American Revolution, General Montgomery’s American army took the fort from the British after a 1775 siege, but British troops took it back the following year.
The fort's location has since been the site of a military base, and from 1952 to 1995, the location of the Collège Royal Militaire.
