Woolworth Building

The building's tower, flush with the main frontage on Broadway, is raised on a block base with a narrow interior court for light. The exterior decoration was cast in limestone-colored, glazed architectural terra-cotta panels. Strongly articulated piers, carried—without interrupting cornices—right to the pyramidal cap, give the building its upward thrust. The Gothic detailing concentrated at the highly visible top is massively scaled, able to be read from the street level several hundred feet below. The ornate, cruciform lobby has a vaulted ceiling, mosaics, and sculpted caricatures that include Gilbert and Woolworth. Woolworth's private office, revetted in marble in French Empire style, is preserved.

Engineers Gunvald Aus and Kort Berle designed the steel frame, supported on massive caissons that penetrate to the bedrock. The high-speed elevators were innovative, and the building's high office-to-elevator ratio made the structure profitable. Tenants included the Irving Trust bank and Columbia Records, which housed a recording studio in the building.
