The Chicago Architecture Foundation is dedicated to advancing public interest and education in architecture and related design. CAF feels that because no art other than architecture expresses so vividly what Chicago is and where it is going and this makes it an important public interest issue. It therefore encourages people to discover Chicago s architecture through walking tours conducted by trained volunteer enthusiasts. It also conducts lunchtime lectures, evening programs and adult education classes at The John Buck Company Lecture Hall Gallery at its center. The Chicago Architecture Center is open Monday through Saturday.
