It was built in 1930 and designed by Walter W. Ahlschlager with Delano and Aldrich.","why_significant":"The nomination calls it one of the finest examples of skyscraper modernism in America and a complete expression of the Jazz Age. Its Art Deco exterior and public interiors, including much decorative work made in France and shown at the 1925 Paris exhibition, remain largely intact. It also reflects progressive city planning in Cincinnati.","narrative":"Carew Tower and the Netherland Plaza Hotel form a block-square complex in downtown Cincinnati, completed in 1930. A common five-story base supports a 48-floor office tower and a 30-story hotel, with a garage tower that was demolished in the late 1980s. Walter W. Ahlschlager and Delano and Aldrich were the architects. The exterior shows Art Deco detailing, including vertical piers, gilded spandrels, rapid setbacks and an observation platform. Inside, the arcade has Rookwood tile panels and silver metal ornament, while the hotel's public rooms use rosewood, imported marble, murals and mirrors. The Hall of Mirrors ballroom and the Palm Court are among them. The nomination describes the complex as one of the finest examples of skyscraper modernism in America, built during the Depression for $33,000,000 and finished in 13 months. Later renovations altered many interiors, but the exterior and major public spaces keep their Art Deco character.","period_of_significance":"1930","architect_builder":"Walter W.
