EXPANSION The new Pierre Lassonde Pavilion of the Musée national des beaux-arts du Québec, realized by the OMA* AMO Architecture P.C. / Provencher_ Roy, imparts a newfound architectural cohesiveness to the Musée and increases by 90% the exhibition space. Linked to the existing museum complex by a 130.6 meters long passageway, the building aims to weave together the city, the park and the museum. In order to create a bond between the Battlefields Park and Québec city, to preserve the historic Saint-Dominique church, to create a persuasive presence on Grande Allée and to integrate harmoniously the new pavilion, the new galleries were stacked, creating a cascade ascending from the park towards the city.
