One Court Square, also known as the Citigroup Building, is a 50-story (209.1 meters or 686 feet) office tower in Long Island City, Queens just outside of Manhattan in New York City. It was completed in 1990 by Skidmore, Owings & Merrill LLP for Citigroup.
The tower is tallest in New York City outside of Manhattan, and the tallest building in Long Island City. WNYZ-LP, also known as Pulse87.7 broadcasts from the top of this building. It is not to be mistaken for the Citigroup Center in Manhattan, which is across the street from Citigroup's main headquarters at 399 Park Avenue. The buildings are one subway stop away from each other along the IND Queens Boulevard Line (E M trains).
