The Citadel of Montreal was a former fortress used to defend the city. It was located at what is now rue Notre-Dame between rue Bonsecours and rue Berri.
Smaller than the one in Old Quebec, the Citadel was built by the French in 1690 replacing the 1658 redoubt at Pointe-à-Callière. It consisted of a barrack structure surrounded by wood stakes palisade and located on a hill along the city's fortification wall. A cannon battery added in 1723.
The fort was demolished by the British in 1821 to allow for the extension of Notre-Dame Street.
