The Pershing Square Building, also known as 125 Park Avenue or 100 East 42nd Street, is a 25-story office building in Midtown Manhattan in New York City. It is located on the eastern side of Park Avenue between 41st and 42nd streets, across from Grand Central Terminal to the north and adjacent to 110 East 42nd Street to the east.
The Pershing Square Building was designed in the Romanesque Revival style by John Sloan and T. Markoe Robertson of the firm Sloan & Robertson, working with York and Sawyer. It was erected within "Terminal City", a collection of buildings located above the underground tracks surrounding Grand Central, and makes use of real-estate air rights above the tracks. The building is located directly above the New York City Subway's Grand Central–42nd Street station.
The Pershing Square Building, as well as 110 East 42nd Street, were built on the site of the Grand Union Hotel. Construction started in 1921 and was completed in 1923. Ownership of the Pershing Square Building passed to several companies; the latest such change occurred in 2010, when SL Green Realty bought the building. It was made a New York City designated landmark in 2016.
