|Address:||Osage Agency Complex, Pawhuska, Oklahoma 040, Osage County 113||County:||Osage|
Two story and rectangular (48′ x 33′), the Osage Agency Administrative Annex is constructed of rusticated and coursed native sandstone. The mortar is beaded. The roof is flat with parapets that are capped with pre-formed concrete blocks. Metal casements, resting on cut stone sills, fill one-half windows. First and second story windows are perpendicularly placed in a plane recessed from the exterior surface and that extends from the top of the second story window to the ground. Perpendicular placement also applies to the exterior doors, the top one leading to the second floor and the bottom one to the first floor.
The Agency Building Annex is significant in that it is one of the few WPA-constructed buildings associated with an Indian tribe–despite the large number of Native American groups in Oklahoma. Architecturally it is unique in terms of its two stories with entryways on each level. That its construction provided job opportunities for destitite whites and Indians during the course of the disastrous national deprression is particularly significant.

“The Osage Tribal Museum, originally constructed in 1872, is housed in a building finished with native Oklahoma sandstone. Originally used as a chapel, school and dormitory as a two-story structure with an auditorium, it was remodeled in 1937 as a one-story building and museum. Each stone was carefully removed and put back. The building’s cupola was retained and is a distinguishing feature of the edifice…
The adaptive reuse of the building to a museum was funded as a Public Works Administration (WPA) project and carried out by the CCC. At the time of its opening in 1938, it was the only museum in the world owned by an American Indian tribe.” 
The Agency is listed on the National Register of Historic Places.
