The museum first opened in November 1998 and was renovated in 2016. Its permanent exhibition, located in the lower level of the Co-Cathedral of Saint-Antoine, houses nine separate sections highlighting our rich historical and religious heritage. Certain objects on display date back to the earliest days of the Saint-Antoine-de-Padoue Parish, which was founded in 1698.
The museum’s 1998 inauguration was the culmination of a nearly three-year effort to seek funding, inventory objects, conduct research, produce a catalogue, and organize the opening. In 2016, committed to make the Co-Cathedral known to future generations, the fabrique decided to renovate the museum and the crypt. Museologists and the Longueuil Historical Society combined their talents and skills to ensure the successful completion of the project.
