The three-story building is constructed of rusticated sandstone blocks with high arched windows. The building is rectangular with a central projection housing the entrance. The stairs once led to the main entrance, but due to security measures the building is now entered through a tunnel under the stairs. Above the stairs is a false balcony supported by Corinthian columns. A pair of arched windows are flanked by a set of Corinthian pilasters supporting a pediment and a frieze bearing the year "1886" in the center with a fanlight above. The central projection is topped with a pediment with a circle light framed by a carved wreath of flags. Standing guard over the entrance is a statue of Justice.
