Its exterior uses Beaux-Arts facades with a pedimented central pavilion, rusticated lower stories and a two-story semi-circular portico supported by colossal Ionic columns. A central dome rises about 150 feet to the top, crowned by a statue of George Washington. Built of Columbia sandstone, granite, brick, iron and steel, the building is described as fireproof and contains fifty-four rooms, including three court rooms. Its interior features Italian marble corridors, a dome with jeweled art glass and frescoes, and polished marble and bronze work. The building is regarded as a fine example of its style and as one of the county's most elegant public interiors. Construction began in 1898 after the earlier brick courthouse and jail were moved, and the cornerstone was laid on March 7, 1899. The building has been used as a courthouse since completion.","period_of_significance":"1900","architect_builder":"F. J.
