Architect/Builder: Layton, Smith and Hawk, W.A. Tackett Associates. The Carter County Courthouse, built in 1910, is a three-story, square, neo-classical building of limestone and granite construction. The building is located on a square, typical of small, mid-westerntowns. The building is seven bays wide, with eight Doric pilasters dividing the bays. The aluminum window frames probably were originally wooden. Modern, metal-framed doors have replaced the original entrances.Photographed by Cosmos Mariner, July 4, 20252. Carter County Courthouse MarkerThe marker is mounted on the right side of the north entrance, below the lamp globes.
The first floor of the courthouse has recessed, arched windows. Framing the windows is a limestone entablature with dentil molding underneath, all below a projecting cornice line. Above this third-story cornice line is a stone balustrade with garland decorations between the rails. On top of the third floor is a coffered-roof cupola. It has four clocks and twelve fluted, Ionic pilasters.
The central feature of the interior is a small-scale, three-story rotunda. The floor has a grid pattern of black and white mosaic tile. The first and second floors have cove ceilings while the third floor has a coffered ceiling. Wide and narrow grained marble are used extensively in the interior on columns, stairs and a five-foot high wainscot.
The Carter County Courthouse is significant because it serves as a center for local government and as an architectural landmark. It is particularly significant because it was designed by the architecturalfirm headed by Solomon Andrew Layton. The courthouse bears his characteristic stamp of sturdy construction and neo-classical styling. Layton was one of Oklahoma's greatest architects and he designed more than 100 public, commercial and educational structures in Oklahoma, including the Oklahoma State Capitol.Photographed by Cosmos Mariner, July 4, 20253.
