History 

Citicorp, the largest bank in the United States at the time, announced plans to build an office tower in Long Island City in Queens in 1985. It was commissioned by the bank to supplement its nearby headquarters at Citicorp Center in Manhattan, and partly financed by the sale of more than 30 floors at Citicorp Center – a deal The New York Times described as "unusual". Because of its proximity to LaGuardia Airport, the plans for the tower were reviewed by the Federal Aviation Administration. The project was approved by the New York City Planning Commission in 1986, and construction began by 1987. Turner Construction was the lead contractor, and Skidmore, Owings and Merrill was the architectural firm. The construction site was occupied by a parking lot at the time, and was previously the site of a hospital. The tower, officially known as One Court Square, opened in 1989 as the tallest building in the borough, surpassing the North Shore Towers in Glen Oaks. It cost $250million. The development benefitted from city subsidies, including tax incentives and concessions on utilities, that aimed to persuade Manhattan firms considering a move to New Jersey to stay in the city. The tax breaks amounted to $97million over 13 years. In exchange, Citicorp funded a $8.5million improvement to the nearby Court Square–23rd Street station and created a  plaza for public use. It also built a 750-car parking garage nearby. Citicorp initially intended to lease part of the building, but eventually decided to occupy the entire space itself. 4,000 employees were expected to work in the building upon completion. A year later, its tax-assessed value was $114million, making it the most valuable building in the borough. At the time, the tower stood alone in a mainly industrial district; The New York Times described it in 2009 as "marooned amid a sea of low-lying warehouses and auto repair shops", and a contemporary review of the building noted that because of its isolation, "we perceive this tower with greater intensity than almost any other skyscraper in the city." The reception in the neighborhood was mixed: many residents feared it would spur overcrowding and rent increases, while businesses were pleased with the prospects for further economic development in the neighborhood. Five years later, the area was little changed. Citigroup sold the building in 2005 to Reckson Associates Realty Corporation for $470million, while maintaining a 15-year lease. A second building, Two Court Square, was constructed for Citigroup on an adjacent lot in 2007, though plans for a third building were scrapped and a commercial district that the city envisioned would coalesce around the new construction did not materialize, in part due to the Great Recession. In 2012, Brooklyn real estate investors Joel Schreiber and David Werner purchased One Court Square for $481 million from Stephen L. Green's SL Green and JPMorgan Asset Management. In 2014, it was purchased by Savanna Realty. In 2020, the Citi logo was removed from the building and replaced with a logo of telecommunications company Altice USA, whose headquarters had been in the building since 2017. Citi's lease expired in the same year. In 2021, Consolidated Edison performed a $5million retrofit of the building's HVAC systems for greater energy efficiency, described as the largest such retrofit of an office building in the company's history. Tenants 
WNYZ-LD (also known as Voice of NY Radio Korea) broadcasts from the top of the building, as do various low power television stations. Since 2017, the building has housed the headquarters of Altice on its top floors. In 2018 the building was selected to provide up to 25 floors to Amazon as part of one of its three Amazon HQ2 locations. However, the Amazon HQ2 location in New York City was later canceled. , Centene leased , and the New York City School Construction Authority was to occupy  across 11 floors starting in 2024. For 30 years, the Queens Library operated a branch on the ground floor of the building, paying a nominal rent of $1 a year. It left the building when its original lease expired. See also
