The AIA Puget Sound Society is an affiliated society of the Archaeological Institute of America, North America's oldest and largest organization devoted to promoting archaeological inquiry and preserving the world's archaeological resources. Established in 1956 as the AIA Seattle Society, the Puget Sound Society serves both professional archaeologists and interested members of the Puget Sound area public. In cooperation with the Departments of Classics at the University of Washington and the University of Puget Sound, the Puget Sound Society co-sponsors an annual lecture series that introduces audiences to the latest archaeological research and discoveries. Lectures, which are free and open to the public, are supported in part by the annual dues paid by Puget Sound Society members. Learn more about the benefits of AIA membership.
