In order to provide an exceptional spiritual, cultural and tourism experience to its millions of visitors and pilgrims, Saint Joseph’s Oratory of Mount Royal is going forward with a huge renovation and construction project that will focus on the preservation of historical buildings, the improvement of visitor experience as well as the sustainable development of the site.


Images below show the architectural concept which is still evolving. Construction is planned to begin in 2018.

The final phase of the shrine’s development project includes the interior design reconfiguration and upgrade of the Basilica’s dome, as well as the renovation of its museum spaces. This will achieve the Basilica architects’ vision by enabling visitors to discover the interior of its gigantic dome and adding an observatory at the very top, which will become Montréal’s highest vista, with a panoramic view of the city and region.

Saint Joseph’s Oratory chose to engage into an architectural competition to receive the most creative ideas, while making the best use of public funds invested in this unique landmark’s future. Four finalists have been announced on February 21 and the winner will be revealed on May 28. The implementation of the project’s final phase is slated to begin in 2020.

  • Development of the “inter dome” of the Basilica :

an exceptional exhibition and projection area.

  • Development of an observation centre :

at the level of the Basilica’s skylight: the highest window onto Montreal !
