The museum showcases one of the City's best-preserved convent complexes, that of the Hospitallers of Saint Joseph, nursing sisters. The complex, built in 1861 according to the plans of the architect Victor Bourgeau, includes their former monastery and garden, the hospital, three chapels, a crypt and the museum, which is housed in the former chaplain's residence. The museum’s collection brings to life four centuries of history focused on the development of Montreal, the practice of hospital care, medicine and pharmacy, as well as on religious art. Guided tours of the garden, the monastery, the chapel and the crypt, where the tomb of Jeanne Mance - co-founder of Montreal and founder of the Hôtel-Dieu - is located, are offered throughout the year.
