A fourteen-story office tower faced in pale brick and terra cotta, filling its corner with a long front of evenly spaced windows. A band lettered UNION ELECTRIC LIGHT AND POWER COMPANY ran above the ground-floor shops. The top story was an arcade of round-arched windows under a deep cornice, with low pyramidal roofs at the corners. A huge steel-framed UNION ELECTRIC sign stood on the roof.
The Union Electric Building rose in 1910 on the southwest corner of Twelfth and Locust, a lot that stood empty in 1909 between Christ Church Cathedral's Schuyler Memorial House and Twelfth Street. It became the headquarters of the Union Electric Light and Power Company, whose name ran in letters across the front and on a giant sign on the roof. The building also held the Shubert Theater. In May 1919, World War I veterans met on the site to found the American Legion, a gathering now marked on the US Bank building that stands there. The Union Electric Building was demolished in 1976.
