It was designed by architect Frank S. Barnum and built around 1904.","why_significant":"The nomination argues the building is a large, prominent and highly intact example of turn-of-the-century Commercial Style architecture. It is also tied to the career of Cleveland architect Frank S. Barnum, and it is the tallest and most prominent commercial building he designed. Its restrained, functional design departed from the more ornate downtown skyscrapers that came before it, and it was reportedly among the first Cleveland buildings to use reinforced concrete floors.","narrative":"Rising nine stories at the southeast corner of Ontario Avenue and Public Square in downtown Cleveland, this steel-frame office building was designed by Frank S. Barnum and completed about 1904. Its two main fronts are clad in pressed brown brick with cast stone trim, with bronze-trimmed storefronts at street level, bay windows on the second and third floors, and a top floor marked by small spires. Inside, the lobby has polished marble and brass, and the upper halls keep their oak trim and terrazzo floors. The building is recognized for its architecture. It is a well-preserved example of early twentieth-century Commercial Style design, plainer and more functional than Cleveland's earlier, heavily ornamented skyscrapers. It is also the tallest and most prominent downtown commercial work by Barnum, a leading Cleveland architect who also designed schools and other commercial buildings. It was reportedly among the first in the city to use reinforced concrete floors. Later changes include a removed entrance pediment and rearranged storefronts.","period_of_significance":"1904-1929","architect_builder":"Barnum, Frank S.; Barnum, F.
