Coulée Grou

Coulée Grou is a national historic site and battlefield located in the Rivière-des-Prairies–Pointe-aux-Trembles district of Montreal. The terrain slopes gently across the landscape near Gouin Boulevard East, positioned approximately 60 meters from a creek that runs through the area.

In 1690, during the French-Iroquois conflicts, Lieutenant de Colombet commanded about 25 French settlers defending against roughly 100 Iroquois warriors. The battle resulted in heavy losses on both sides and became a turning point in the region's colonial story.

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.
