The Old Washington County Courthouse in Oklahoma is a reinforced concrete building that was built in 1913. It was designed by P.H. Weathers in Second Renaissance Revival style. It was listed on the National Register of Historic Places in 1981.
Washington County was founded in 1907, but it was not until 1912 that a bond issue to fund the courthouse was passed, on the third attempt.[1]
