The Centre Canadien d'Architecture/ Canadian Centre for Architecture is a museum and study centre devoted to the art of architecture past and present. It is founded on the conviction that architecture, as part of the social and natural environment, is a public concern. The CCA's activities are local, national, and international in scope. They are based on a unique collection of works of art and documentation from cultures throughout the world and from all disciplines that create and intervene in the built environment - including architecture, urban planning, and landscape design.
