The Noble County Courthouse is located in Caldwell, Ohio. The building was constructed in 1933-1934 and designed by Charles J. Marr. The building was constructed with red brick manufactured at nearby Ava, Ohio to control costs of construction. The windows are flat rectangular panels with either an arch pediment and decorative natural stone keystones or a slanted pediment. The building may be entered by a few stairs leading to a small recessed porch with archway openings. The Noble County Courthouse is currently the largest building in Caldwell.
