Coulée Grou, National historic site and battlefield in Rivière-des-Prairies–Pointe-aux-Trembles, Montreal, Canada.

Coulée Grou is a national historic site and battlefield in the Rivière-des-Prairies–Pointe-aux-Trembles district of Montreal, named after Jean Grou, a New France pioneer who settled here around 1650. The site lies near a ravine (coulée) that runs through the area, close to Gouin Boulevard East. A bilingual monument commemorates the 1690 battle between French soldiers and Iroquois warriors.

On 2 July 1690, Lieutenant de Colombet led about 25 settlers from Pointe-aux-Trembles against roughly 100 Iroquois descending the Rivière des Prairies by canoe. The French fired first, then fought hand to hand; some 30 Iroquois were killed. Colombet and eight of his men died, six were taken prisoner, and Jean Grou was burned alive with companions among the Oneidas. The dead were buried on the spot and moved to the cemetery on 2 November 1694.

The site honors French settlers who fought to protect their homes and livelihoods in this area. A bilingual monument preserves their memory and tells the story of their struggle to those who visit.

The commemorative monument is located near Gouin Boulevard East and can be found easily using GPS navigation. The site is open to visitors who want to explore the grounds and understand the historical significance of this location.

Jean Grou, the original landowner after whom the site is named, was taken prisoner during the battle. He and three farm workers died tragically, and their fates remain inseparably linked to this place today.
