The main building is a three-story building, built during 1909-1910 of red brick with white stone trim. It is 50 by 160 feet (15 m × 49 m) in plan and served as a combination school and dormitory, and was built at cost of $100,000.[3]
The second building, built in 1918, is also three stories but is more modest, and is 32 by 80 feet (9.8 m × 24.4 m) in plan.[3]
In 1976 the two buildings served as headquarters and museum of the Red River Valley Historical Society.[3]
Beginning in 1975, the building functioned as the Choctaw Nation's administrative headquarters until 2018 when the headquarters was relocated to a newly constructed building. The building still houses some Choctaw Nation employees, but remains largely empty since the move.[4]
