The chapel now also houses the Marguerite Bourgeoys Museum, dedicated to the life of St. Marguerite Bourgeoys and to the early history of Montreal and the chapel site. Below the chapel, the crypt is being excavated as an archeological site, which visitors can see. First Nations and French colonial artifacts have been discovered, along with the foundations of the first chapel and the fortifications of the colony. The church's prominent spire can also be climbed, offering views of the Old Port and Saint Lawrence River. In 2005, Marguerite Bourgeoys's mortal remains were brought back to the church, where she now lies in the sanctuary.
