When county commissioners finally replaced the courthouse burned in the Civil War, they obtained the services of Wheeling architect C. C. Kemble. His two-story brick building is a restrained exercise in classicism. Blind arches, framed in stone, decorate the first story of a projecting entrance pavilion. A stone belt course carries around the entire building, firmly delineating the first story from the piano nobile above and providing a base for unadorned brick pilasters that separate bays and define corners. A triangular pediment caps the pavilion, while a hipped roof covers the body of the courthouse. A large wooden belfry with paired, louvered openings on each face rises behind the pediment and is topped with a convex dome.
