The Center for Architecture performs the charitable and educational work of the Philadelphia chapter of the American Institute of Architects (AIA) and serves as the physical home for the Chapter in Center City Philadelphia. The Center was envisioned with three core principals in mind: Public Engagement, Collaboration, & Design Excellence. The Center is an exhibition gallery, studio, museum, interpretive laboratory, tourist destination, reception hall, and classroom. The Center offers walking tours, exhibitions, lectures, and workshops on architecture, urban planning, and design all throughout the year; many programs are offered for free. Browse our selection of architecture books, designer gifts, and creative toys at the AIA Bookstore & Design Center, located at the front of the Center. The Center is also home to the Philadelphia chapter of the AIA and the Community Design Collaborative.
