Battle of Rivière des Prairies / Battle of Coulée Grou National Historic Site of Canada

Battle of Rivière des Prairies / Battle of Coulée Grou National Historic Site of Canada is located on a rolling, partially treed landscape near the coast of the Island of Montréal in Québec. It was the site of a battle between a group of Iroquois and a group of French settlers in 1690. There are no extant remains of the battle; however, the site is marked by a Historic Sites and Monuments Board of Canada commemorative plaque that is located approximately 60 metres from the creek on Gouin Boulevard. Official recognition refers to the irregular polygon of the battle site at the time of designation.

Battle of Rivière des Prairies / Battle of Coulée Grou was designated a national historic site of Canada in 1924 because:

- it is the site of a battle, in 1690, between the French and the Iroquois.

On July 2 1690, the Sieur de Colombet, a former lieutenant in the French army, was alerted to the presence of a group of Iroquois on the nearby Rivière des Prairies, prompting him to gather 25 settlers to investigate. They traveled to the property of Jean Grou, near the creek bearing his name, and fired on the canoes of the Iroquois, killing four. The Iroquois, numbering roughly 100, landed and engaged in combat with the French. In the ensuing battle 15 French and 30 Iroquois were killed or taken prisoner.
