Architectural Heritage Center

The Architectural Heritage Center (AHC) in Portland, OR is a 501c3 organization dedicated to advancing knowledge and appreciation of Portland’s history and architecture in order to protect and preserve the significant architecture and cultural heritage that make Portland special. We accomplish this through education and advocacy. The AHC owns and operates a vibrant educational center, gallery, library/archives, and offices in a restored historic building in Portland. In addition, our work extends actively into the community through direct advocacy, an extensive menu of walking tours throughout the city, and productive partnerships with other institutions. The AHC is owned and operated by the non-profit Bosco-Milligan Foundation, established in 1987.
