Our History Formerly known as the Chicago Architecture Foundation, the Chicago Architecture Center is a nonprofit cultural organization with tours, exhibitions, programs and events for all ages. Our mission is to inspire people to discover why design matters. The Chicago Architecture Center (CAC) was founded in 1966 as the Chicago Architecture Foundation to save the historic Glessner House. Since then, the CAC has grown to become one of the largest cultural organizations in Chicago. For more than 50 years, our educators, 450 volunteer docents and 150 guest services volunteers have shared the stories of Chicago architecture with millions of Chicagoans and visitors. In 2017, the CAC served nearly 690,000 people. Starting August 31, visit the CAC at 111 E. Wacker Dr. to view our 4,250-building scale model of Chicago, shop in our award-winning store or participate in a fun family event in our ArcelorMittal Design Studio. Or choose from 85 tours by boat, walking, bus or “L” train. Tours depart daily and are led by CAC's expert, volunteer docents. Every October, check out the CAC's free annual Open House Chicago festival. Proceeds from the CAC’s tours and store, as well as grants, sponsorships and donations, support our educational mission.
