Harding County Courthouse

The Harding County Courthouse, located on Pine St. in Mosquero, is the county courthouse in Harding County, New Mexico. The courthouse was completed in 1922; while the building had existed previously as a school, it was extensively remodeled to become the county courthouse. It is considered the grandest public building ever built in the county, the smallest in the state by population. The two-story building has a Classical Revival design with modest decoration; its main features include an entrance framed by piers and a cornice, pilasters above the entrance, and an egg and dart entablature. The courthouse grounds make up one of the only two dedicated public spaces in the county, along with the public square in Roy.

The courthouse was added to the National Register of Historic Places on December 7, 1987. It is one of 14 New Mexico county courthouses that were reviewed for their historical significance in 1987.
