Fort Sill's Old Post Guard House, a limestone building established in 1872 and completed in 1873, began as cavalry barracks before serving as a military stockade and later a museum. Closely connected to the Army's frontier era and federal Indian policy, it held tribal leaders and American Indian prisoners of war as Fort Sill assumed a larger role in controlling and resettling Native peoples. It is especially associated with the imprisonment of the Kiowa chiefs Satank, Satanta, and Big Tree after the 1871 Warren Wagon Train raid. In 1934, the building became the formal home of Fort Sill's museum, and it remains a rare survivor tied to confinement, resistance, and assimilation on the southern Plains.
