The Blaine County Courthouse in Watonga, Oklahoma was built in 1906, the year before Oklahoma received statehood. It has been asserted to be "one of the most imposing structures in Watonga" and it "serves as a landmark for both the town and the county," Blaine County. It has a large central dome, a pedimented entrance, and a pediment above its cornice whose tympanum is painted with spirals and the date "1906". Its front facade also features an arcade of three arched windows on the third and fourth story levels.
