3. The Helmsley Building Is Designed by the Architects of Grand Central Terminal

William Vanderbilt (Cornelius’ son and owner of New York Central Railroad) hired his cousin’s firm, Warren and Wetmore, to design 230 Park Avenue. The firm was also behind the design of Grand Central Terminal. Today, the marble, steel and bronze details still capture the essence of Park Avenue and Terminal City, and its easy to see how the Helmsley Building and Grand Central Terminal were conceived under the same conceptual idea.
