About the Museum

Five Oaks Museum, formerly known as the Washington County Museum, is a history museum in Washington County, Oregon, United States. It is located at the Rock Creek campus of Portland Community College (PCC), north of Beaverton, Oregon. From 2012 to 2017, its public exhibit space was located in downtown Hillsboro, Oregon, before it was moved back to PCC, its pre-2012 location and where the museum's research facility had already been located. Opened in 1975, the museum is operated by the Washington County Historical Society with a mission of preserving the history of the area. The museum's site at PCC's Rock Creek Campus also includes a research library and is home to the original Washington County Jail built in 1853.
