2020 marks the 300th anniversary of the first French trading post established in 1720 on the current site.
Fort Témiscamingue was a major fur trading post for over 200 years. In the 17th and 18th centuries, it played a strategic role in the fight between the French and English for the monopoly of the fur trade in the upper Ottawa River and the Hudson Bay watersheds.
The national historic site, although heavily vegetated, has been shaped by longstanding human occupation, whether Algonquin, French, English or Canadian. Many remains bear witness to this. It should be added that the current face of the vegetation landscape is largely inherited from human activity due to the forest harvests of the 19th century.
