🧭 Fort Frontenac

Fort Frontenac was a French trading post and military fort built in July 1673 at the mouth of the Cataraqui River where the St. Lawrence River leaves Lake Ontario, in a location traditionally known as Cataraqui. It is the present-day location of Kingston, Ontario, Canada. The original fort, a crude, wooden palisade structure, was called Fort Cataraqui but was later named for Louis de Buade de Frontenac, Governor of New France who was responsible for building the fort. It was abandoned and razed in 1689, then rebuilt in 1695.
