in the Willamina vicinity, has been listed on the National Register of Historic Places since 1971. The address of the site is withheld, however the Oregon Parks and Recreation Department runs the undeveloped Fort Yamhill State Heritage Area in partnership with Polk County and the Confederated Tribes of the Grand Ronde. As there are no remaining buildings at the fort grounds except a relocated Officer's Quarters building, the parks department plans to reconstruct some of the fort buildings, including a new blockhouse. In 2005 and 2013, Fort Yamhill served as the site for the Oregon State University historical archaeology field school. Students worked to uncover the foundations of Fort-era buildings.
