October 2011. The new building is connected to the museum complex through a tunnel under avenue du Musée, as an extension of the link under Sherbrooke Street. The tunnel brings the visitor to the floor under the Erskine and American church to the first phase of the exhibition, which continues through five superimposed rooms constructed at the back of the church. This arrangement makes it possible to present the collection in generally chronological order. Descending through each vertical level, the visitor travels through cultural time, from the 17th century French colony on the fourth level, to the mid-20th century modern period in the segment under the church. The top floor of the pavilion is devoted to Amerindian and Inuit Art.
At each level, the architecture allows more and more natural light to filter in, up to the top where an atrium window with a view of the mountain and the city forges a strong link with the environment. Another aspect of the project was to transform the church into a concert hall able to accommodate chamber orchestras as cultural and educational events. This particular feature allows the Museum to restore the church’s function as a public space. In addition to making a large collection of stained glass available, the conservation of the church affords a unique opportunity to create a structure whose great heritage value forms a legitimate part of the Museum’s permanent collection
