Fort Frontenac National Historic Site of Canada is an archaeological site located beneath the intersection of Ontario Street and Place D’Armes in Kingston, Ontario. The site extends under four stone buildings, constructed during the 1820s as part of the former Tête du Pont Barracks on the southern portion of ground previously occupied by the original French fort. While these four buildings are part of a complex currently referred to as Fort Frontenac, only a fragment of the original fort can be seen today. Sections of the west and north limestone curtain walls are exposed on a traffic island at the intersection of Ontario Street and Place D’Armes. Official recognition refers to the footprint of Fort Frontenac.
