The CCA should be a destination museum for anyone interested in architecture, professional or not. The massive building also serves as a research center and is recognized internationally as a leader in public awareness, scholarship, and innovation in architecture. Exhibitions aim to connect how we think about architecture, how it is practiced in the modern day, and how societies and cultural differences influence changes over time. There are usually several temporary exhibitions on display (they change regularly), plus permanent collections that include prints and drawings, sketches, artifacts, and publications, some of which date back more than 600 years. Nearly all captions and text are in English and French. Across the street on the opposite side of boulevard René-Lévesque is a sculpture garden that provides a serene contrast to the hustle and bustle of the surrounding city.
