Fort Yamhill State Heritage Area

Park History

Fort Yamhill was a United States Military outpost that was in operation from 1856 to 1866 and was located on the eastern border of the Grand Ronde Indian Reservation. The purpose of the fort was to protect and control Native Americans on the reservation.  Many settlers in Oregon supported a “war of extermination” towards the native people. The fort acted as a buffer and eased tensions between Native Americans and white settlers. The army also policed the Native Americans on the reservation, enforced agency rules, suppressed inter-tribal disputes and returned escaped American Indians to the reservation.

On average 80 men and four officers manned the garrison, consisting of 24 buildings. The regular army operated the fort from 1856—1861 and were then called back East to fight in the Civil War. However, the fort was still needed to act as a buffer, as well as provide a Union presence in Oregon & monitor secessionist activities. Volunteer soldiers ran the garrison from 1861—1866. When the fort closed, the military auctioned off the buildings, many of which were taken apart for materials or moved. Two buildings from the fort exist today: the blockhouse, which was moved to Dayton, OR in 1911, and an officer’s quarters, which is at the park and under restoration.

Today, Fort Yamhill is an amazing archaeological site. Archaeologically, it is one of the best preserved forts in the Northwest from this period. Even though the buildings are gone, the “footprint” of the fort is still intact and beautifully preserved. Recent excavations have revealed building foundations, the kitchen fireplace, the bakery oven, as well as numerous military & domestic artifacts. The archaeological research is being performed by Oregon State University’s Archaeological Field School.

Fort Yamhill State Heritage Area was opened in 2006 to protect and interpret the natural and cultural resources of the site. Park facilities include a 1/2 mile interpretive trail, picnic areas, scenic viewpoints, restrooms, and interpretive signage. The park is in its initial stages of development and includes ongoing archeological research and building restoration that enrich the visitors’ experience and help bring history to life.
