Description of Historic Place

The National Arts Centre is a complex structure of irregular plan whose design is based on the triangle and hexagon, from the overall composition down to decorative details. The building houses several performance spaces, rehearsal halls, dressing rooms, a workshop and prop room, offices, restaurants, reception spaces and subterranean parking garage. Designed in the Brutalist style, the National Arts Centre is constructed of poured reinforced concrete and covered with precast panels of exposed Laurentian-granite aggregate concrete with a variety of textures. The visually dominant components of its irregular design are the three main performing spaces that rise above a series of terraces.

Heritage Value

The National Arts Centre was designated a national historic site of Canada because: it is an outstanding example of a performing arts centre in Canada for its overall design, its highly successful integration into its urban setting, its succession of interior spaces to create dramatic effect, its unique combination of performing spaces and the progressive designs of each one, and its integration of contemporary works of art as part of its design; it is an outstanding example of a building illustrating the positive consequences of Canadian federal policy on the performing arts during the second half of the 20th century, considered, in the words of Prime Minister Lester B. Pearson, as a "national institution"; it is an example of state-of-the-art performing spaces and technology at the time of construction, in particular for the aesthetic and technical design of Southam Hall, which is an exceptional example of a medium-sized multi-purpose auditorium representing an inspired collaboration between architect and acoustician.

The National Arts Centre was both a major cultural as well as a major architectural achievement for the country. The structure, built in 1965-69 to designs by the architectural firm of Affleck, Desbarats, Dimakopoulos, Lebensold and Sise, reflects the rise of state support to the arts in the second half of the 20th century. It was built as part of the celebrations of for the one-hundredth anniversary of Confederation, and it was intended to herald the cultural achievements of the nation in the fields of the performing arts. The National Arts Centre is also a component of the Confederation Square National Historic Site of Canada.
