The Harrison County Courthouse in Cadiz, Ohio, United States, was constructed during 1893 to 1895 by Joseph W. Yost. The courthouse mirrors others of his design, with large arched windows and a central clock tower domed and topped with a statue of Justice. The porches to the entrances are covered with a balcony. The building's corners are partially separate structures topped with mansard roofs, while post and lintel structures, topped with pediments, are placed on each side of the corner structures. The entire exterior is constructed of stone.
