The USTA National Tennis Center (NTC) in Flushing Meadows, New York is the home of the US Open. It is the world’s largest public tennis facility.
It opened in 1978 when the United States Tennis Association turned a former World’s Fair site into the USTA NTC, located just a few minutes from Manhattan.
The NTC is open to the general public throughout the year. It has 33 outdoor and nine indoor courts. The 33 outdoor courts do not include the Arthur Ashe, Louis Armstrong and Grandstand courts. Arthur Ashe court, with a seating capacity of 23,000, is widely recognized as one of the world’s greatest sports and entertainment venues. Louis Armstrong has a seating capacity of 10,000 and Grandstand seats 6,000.
There are 22 field courts located within the gates of the tennis center and 11 additional courts built by the USTA at Flushing Meadows-Corona Park, which is adjacent to the main entrance. These 11 courts are run by the New York City Parks Department and are used as practice courts during the US Open.
NTC basically operates as a community tennis facility. Besides the Grand Slam event, it hosts a number of events throughout the year for various categories -- children, teens, adults, physically challenged and seniors.
