Fort Pontchartrain du Détroit or Fort Detroit (1701–1796) was a fort established on the north bank of the Detroit River by the French officer Antoine de la Mothe Cadillac and the Italian Alphonse de Tonty in 1701. In the 18th century, French colonial settlements developed on both sides of the river, based on the fur trade, missions, and farms.
