Welcome to the Architectural Heritage Center

The Architectural Heritage Center is a non-profit resource for historic preservation owned and operated by the Bosco-Milligan Foundation. As “home base” for heritage conservation in the Portland, Oregon metro area, the AHC hosts dozens of programs, tours, and exhibits each year which help people appreciate and preserve older and historic buildings, neighborhoods, and traditional commercial areas. The AHC is also steward of one of the largest collections of architectural artifacts in the United States, maintains a research library, and hosts art exhibits which honor the historic and creative legacy of its founders, Jerry Bosco and Ben Milligan. The work of the AHC is made possible only through contributions from a community of members who support preservation of our historic building traditions, and the craftsmanship, culture, and environmental sustainability they represent. About 82% of the organization’s budget is given by individuals. The AHC thanks them, and invites you to join or contribute now!
