The foundations of the original Notre-Dame-de-Bon-Secours Chapel

Situated beneath the nave of the Notre-Dame-de-Bon-Secours Chapel and accessible by the crypt, an exceptional archeological site awaits the visitors!
During excavations made between 1996 and 1997, archeologists made many discoveries each one more fascinating than the last. You can see (upon reservation) traces of Amerindian encampments dating back more than 2000 years, physical signs of the terrible fire that destroyed Marguerite’s first chapel, its remnants, and the imprint by the wooden fence that formed the fortification of Ville-Marie in 1709.
