Oregon Historical Society is at 1200 S.W. Park Ave. Located in downtown’s South Park Blocks, the museum features original and traveling exhibitions that tell stories of the people, places and events that have shaped Oregon and American history. Monthly programs are often free and open to the public and feature Oregon authors, historians and artists. The society's research library is the primary resource center for information about state history.
Eight-story-tall trompe l'oeil murals of Western themes by Richard Haas grace the outside of the building.
