During the depths of the Great Depression, the city constructed an Art Deco building initially named Monument National. The multi-purpose structure housed offices, a swimming pool and a concert hall. Since then, the House of Music has evolved considerably. Palais Montcalm offers several venues for the performing arts including the Raoul-Jobin Room (concert hall), the Youville Room (theater) and the Gallery (art exhibition). Montcalm Palace is also home to the National Opera of Québec and Les Violons du Roy (chamber orchestra).
