Notre-Dame Basilica of Montreal

Client: Fabrique de la paroisse Notre-Dame-de-Montréal

Location: 110 rue Notre-Dame O., Montréal, QC

Year of project completion: Ongoing

Built between 1824 and 1829, the Notre-Dame Basilica replaced a smaller church originally in this spot in Place d’Armes. Several interventions over the last hundred years have kept the building in acceptable condition, however the limestone of this basilica, which is nearly 200 years old and 160 years old for the two bell towers, is for the most part at the end of its useful life. DFS is currently involved in a major project to restore the main façade as well as the two bell towers, which were built between 1841 and 1843.

The three-phase refurbishment and restoration programme began in 2019 and is scheduled to continue until 2025.

Along with these exceptional mandates also comes a great responsibility to act with discernment and moderation in order not to alter the heritage value of these unique historical buildings.

After conducting a thorough investigation of the massive masonry structure and the ability of the cut stones to further withstand severe weather conditions, the difficult decision was made to replace a significant number of these limestone stones.
