The site of the Orford Arts Centre equally possesses great historical and architectural value. Today it is one of the few places in Quebec where you can find a significant concentration of buildings designed in the modern expressionist style. The Gilles-Lefebvre Concert Hall (1960), L’Homme et la Musique Pavilion (1967) and the J.A. DeSève Pavilion (1968) are all part of a formal renewal in Quebec architecture that coincided with the entry of Quebec society into modernity. The dynamic shapes of its pavilions and the originality of the methods used by architect Paul-Marie Côté (1921-1969) make these buildings historical masterpieces of modern Quebecois design.
There is also something extremely interesting and unique about the architecture of the Gilles-Lefebvre Concert Hall, and the L’Homme et la Musique and J.A. DeSève pavilions: their designs are all linked to music. The Gilles-Lefebvre Concert Hall is in the shape of a grand piano. L’Homme et la Musique Pavilion is in the shape of an organ case. And the J.A. DeSève Pavilion is in the shape of the musical note Fa.
