The Jonathan M.Wainwright Memorial VA Medical Center (VAMC) is located on the grounds of what was once Fort Walla Walla, one of the oldest military posts established in the Pacific Northwest (1856-58). In 1921-22, the facility was converted for use as a hospital and came under the jurisdiction of what is now the U.S.Department of Veterans Affairs (VA). Constructed between 1858 and 1906, the remaining historic buildings from the military era include the officers’ quarters, stable, and infantry barracks—among the oldest structures in the state. Additional buildings constructed in the 1920s and ‘30s for hospital use remain today.
