Mansfield of Illinois created one of the finest examples of Romanesque Revival architecture in the state. Square and round towers, conical roofs, and arched openings create a lively interplay of shapes. The six-stage clock tower soars from the southwest corner; its pyramidal roof was restored in 1985. The building’s smooth brick walls are trimmed with quarry-faced limestone providing both a sense of weight and textural contrast. Rugged limestone marks the foundation and the massive entrance porches, which have balustraded roof decks and arcades supported by squat marble columns. Rough-cut quoins and window surrounds, decorative stonework in the gable ends, dentils along the cornice, and smooth-faced stonework around the doors opening onto porch roofs provide textural contrast. Inside, the second-floor courtroom features two murals by Franz Rohrbeck, a German immigrant to Milwaukee, expressing the theme of justice.
