The Fort de l'Île Sainte-Hélène, a historic site on Saint Helen's Island in the city of Montreal, Quebec, was constructed in the early 1820s as an arsenal in the defensive chain of forts built to protect Canada from a threat of American invasion.Although not heavily fortified, it served an important purpose as the central artillery depot for all forts west, and in the Richelieu River Valley, known as the Valley of the Forts.
