Adair County Courthouse, County courthouse in Stilwell, United States.

Adair County Courthouse is a classically inspired Art Deco building completed in 1930 in Stilwell, designed by Haralson & Nelson and built of limestone, steel and concrete. Its cornice carries molded bas-relief figures of American Indians in full headdress.

The current courthouse is the fourth building to serve Adair County in Stilwell. From 1902 to 1908 a two-story wood-frame schoolhouse held the courts; a brick courthouse followed in 1908, then a native-stone building in 1920, which burned on December 30, 1929. Haralson & Nelson designed the replacement, completed in 1930 and listed on the National Register of Historic Places in 1984.

The cornice of the Adair County Courthouse carries molded bas-relief figures of American Indians in full headdress, a detail visible from the street below. The building stands in Stilwell, seat of Adair County, a county whose population is largely Cherokee. The 1992 marble war memorial on the lawn lists Adair County residents killed in World War I, World War II, the Korean War and the Vietnam War.

The building is centrally located on Courthouse Square and is easy to reach while exploring downtown. Visitors should note that it remains an active courthouse with regular operating hours during business days.

The 1992 marble memorial on the courthouse lawn lists the names of every Adair County resident killed in World War I, World War II, the Korean War and the Vietnam War. It stands apart from the 1930 building and records four conflicts in one monument.
