was placed on the 18th floor. Elements of several architectural styles were used, including the Beaux-Arts base, Baroque midsection, and the Renaissance Revival and neoclassical decorations on top. Robert A. M. Stern wrote in 1983 that Hardenbergh's blending of styles—as used on another of his commissions, the Plaza Hotel near Central Park—demonstrated a "masterful combination of gemuetlichkeit and Classical rigor". Illumination of the facade was a key part of the Hardenbergh design for the building: lamps were suspended beneath the cornice and on the roofline, and the storefronts at ground level were also illuminated. Even the use of limestone on the facade, instead of brick, was conducive to the illumination, as the limestone reflected the light generated by these lamps. The Real Estate Record & Guide cited the building's exterior illumination scheme as being "as interesting an example of decorative exterior lighting as has ever been attempted in New York City." Such illumination had been used previously in the city, notably at Luna Park and Dreamland amusement parks at Coney Island, as well as during the 1909 Hudson Fulton Celebration, when illumination was placed on the East River bridges and on major structures such as the Singer Building and the Plaza Hotel. However, it was still relatively rare for office buildings to be illuminated each night, though such lighting schemes were commonly tested at the premises of power companies. The lighting scheme was scrapped in the 1920s when the Warren and Wetmore tower was built. Warren and Wetmore structure The design of the 26-story tower at Irving Place and 14th Street was similar to the Metropolitan Life Insurance Company Tower at Madison Avenue and 23rd Street. Two 18-story wings wrapping the tower were designed in a similar manner to Hardenbergh's structure. The decoration was similar to that of Hardenbergh's design, but with less detail. The base contained a three-story colonnade in the Doric style. Throughout the Warren and Wetmore section of the building, there is light-inspired ornamentation including depictions of urns, torches, lamps, thunderbolts, and suns. These decorations symbolize Con Ed's function as a power company, and by extension, a provider of light. Rising above the base was a tower that was set back from the street, as required by the 1916 Zoning Resolution. The ornamentation at the tower's peak included urns and obelisks, which were normally associated with funereal aspects, and was modeled after the Mausoleum at Halicarnassus. These
