The Helmsley Building is a 35-story skyscraper at 230 Park Avenue between East 45th and 46th Streets, just north of Grand Central Terminal, in the Midtown Manhattan neighborhood of New York City. It was built in 1929 as the New York Central Building and was designed by Warren & Wetmore in the Beaux-Arts style. It was the tallest structure in the "Terminal City" complex around Grand Central prior to the completion of what is now the MetLife Building.
The Helmsley Building carries vehicular traffic through its base: traffic exits and enters the Park Avenue Viaduct through two portals passing under the building. The lobby of the building is between the vehicular portals. Flanking the viaduct's ramps are passageways connecting 45th and 46th Streets, with entrances to Grand Central Terminal.
