This is a rare, free-standing triangle building. As early buildings in Pawhuska were constructed, a triangle-shaped piece of land was left in the middle of town. It was a park with a two-story bandstand in the center. In 1915, this five-story, "flat-iron"
City Hall is located in the building which was the first Osage Tribal Council House. The present stone building, built in 1894, is the second building, as the original was destroyed by fire. The bell in the tower was used to call councilmen to meetings.
The First National Bank is on the site of the second Osage Agency as the original log cabin in the valley burned. The Osage Tribe built a hand-cut sandstone two-story building which housed the agency and commissary. In 1924, this current structure was built.
