The courthouse somewhat resembles the old U.S. Capitol before the Civil War additions. The rusticated foundation is hidden behind a balustrade that wraps around the entire structure. The ground floor consists of smooth stone and arched windows, each with a decorative keystone. The entrances are accessed by a small recessed portico with three large arches. Above the entrances are four colossal Corinthian columns inside a recessed panel. Rectangular windows spread out on either side of this panel, lighting the various rooms within. An entablature supports the flat roof and a balustrade lines the roof. Instead of a typical dome, the building is crowned by a large dome containing a skylight illuminating the stained-glass window inside.
