In 1983, then-developer Donald Trump commissioned renowned architect Philip Johnson and his partner John Burgee to design an ambitious residential condominium project on Madison Avenue near 60th Street in New York City. The proposed $200 million development, a 60-story tower featuring six spires with gold-leafed, coned, and crenelated tops, was to be a joint venture between the Trump Organization and Prudential Insurance Company of America. The design was notable for its castle-like elements, including drawbridges and a moat, reflecting what Johnson described as Trump’s distinctive and audacious tastes.

Despite generating early buzz, the project was never realized. After initial enthusiasm, the developers abandoned the plans later that year, citing concerns over costs and other factors. The site was ultimately sold, and the project quietly faded into obscurity. A set of 64 original drawings and a model of the development, which had been slated for disposal, were instead preserved by Ivan Zaknic, a professor emeritus of architecture at Lehigh University and former archivist for Johnson and Burgee’s firm. Zaknic later chose to make these materials public to highlight the project’s architectural and historical significance.

Johnson, who died in 2005, had praised Trump in a 1984 interview for his bold instincts, calling the castle “his most exciting project” and noting a sharp contrast with more conventional developers driven by market research. “Trump is mad and wonderful,” he said, underscoring the distinctive character of the proposed design.

John Burgee recalled that Trump abruptly ended the project upon selling the property. “He called and said, ‘Well, I’ve sold the property, and I’ve gotten rid of it, so the project’s over—forget it,’” Burgee said. The architecture firm was left with an unpaid bill, eventually receiving only partial payment for their work.

The “Trump Castle” name later became associated with a hotel and casino in Atlantic City, which Trump acquired from Hilton Hotels in 1985. That property was renamed Trump Marina in 1991 and was sold in 2011 to the hospitality company Landry’s, which rebranded it as Golden Nugget.

The Madison Avenue project’s preservation owes much to Zaknic’s efforts while working on the archives for Johnson and Burgee’s office during the mid-1980s. At the time, the architects were preparing materials related to other landmark projects such as the AT&T Building, also on Madison Avenue.

Burgee described Trump’s approach to business during their collaboration as direct and efficient, with brief meetings reflecting an “impatient” style. Nonetheless, Trump was noted for being personable and straightforward in his dealings.

The unfinished “castle in the air” now provides a glimpse into an unrealized chapter of New York’s architectural history and offers insight into Trump’s early real estate ambitions and aesthetic preferences. The project remains an intriguing example of the intersection between architecture and ambitious urban development plans that never came to fruition.
