The final phase of the Major Development Project offers an ambitious transformation. Opening the Oratory's dome and its observation point allows Montréal to discover one of its most iconic landmarks in a new way, while strengthening its role as a place of heritage, culture, spirituality and tourist appeal.
The new museum space, the ascent through the dome, the interpretive features and the gradual discovery of a 360-degree panorama of the city will make for a distinctive experience, destined to become a must-see.
