The Greer County Courthouse, on Courthouse Sq. in Mangum, Oklahoma, is a courthouse which was built in 1906. It was listed on the National Register of Historic Places in 1985.
It is a three-story red brick building with granite and limestone trim. It was built with an "elaborate copper-covered dome centered on the top, but. [sic] it was removed in the 1940s because the weight of the dome caused structural damage to the building."[1]
