The Somervell County Courthouse was erected in 1893. John Cormack of San Antonio, Texas, designed the building, and it was built with native limestone in the Romanesque Revival style. The structure is typical rectilinear design with a central hallway placed on the north/south axis. The east and west facades are divided into five-part compositions, while the north and south facades are broken into three parts. Limestone circular arches framing the doors, windows, water table, and belt courses further embellish the rusticated stone of the building. A belt course and limestone dentils decorate the cornice area. The central portion of each façade is slightly projected and topped with a pediment that intersects the Mansard roof. A clock tower completes the composition of the structure.

The roof and tower were greatly altered through the years and a tornado did much damage in 1902. In 1986-1987, the courthouse underwent a complete renovation. The asbestos roof covering was replaced with a dark metal covering, which is more sympathetic to the original roof material. The limestone chimneys and arched ventilating dormers were rebuilt. The clock tower was also restored, and the decorative iron railing was replaced on the roof. On the interior, the dropped ceiling, wood paneling, and carpet were removed, and a wood wainscot and more historically sympathetic carpet were installed. (Information from Courthouse files)
