Plan of the fort of 1665

1665-1666: 1,200 men from the Carignan-Salières regiment build a series of five wooden forts, including Fort Sainte-Thérère, to protect the young colony and conduct war in Iroquois territory southwest of Lake Champlain.

1667: Abandonment of Fort Sainte-Thérèse.

1747: Building of the second Fort Sainte-Thérèse.

June 1760: Destruction on June 16 by American Rangers during the Seven Years’ War (1756-1763), and immediate reconstruction of the fort by the French army.

August 1760: After the fall of the fort on île aux Noix, the French army withdraws from the fort and burns it down to avoid its capture by British troops. The spot is retaken by the British, who abandon it permanently after the Conquest. The fort would never again be rebuilt.

More than 150 years later, the fort’s exact location had been forgotten.
