The building was the tallest in Queens from its completion until the topping out of Skyline Tower in 2019, and for many years was the only skyscraper in Long Island City.

It is now home to telecommunications firm Altice USA, whose logo adorns the top of the building, among other tenants.

One Court Square was designed by Raúl de Armas of Skidmore, Owings and Merrill and is owned by Savanna.

Citicorp, the largest bank in the United States at the time,[1] announced plans to build an office tower in Long Island City in Queens in 1985.

[20] In exchange, Citicorp funded a $8.5 million improvement to the nearby Court Square–23rd Street station and created a 16,000 square feet (1,500 m2) plaza for public use.

[14] Citicorp initially intended to lease part of the building, but eventually decided to occupy the entire space itself.

[22] 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",[23] 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.

[24] Citigroup sold the building in 2005 to Reckson Associates Realty Corporation for $470 million, while maintaining a 15-year lease.

[30] WNYZ-LD (also known as Voice of NY Radio Korea) broadcasts from the top of the building, as do various low power television stations.
