The New York Coliseum was a convention center that stood at Columbus Circle in Manhattan, New York City, from 1956 to 2000. It was designed by architects Leon Levy and Lionel Levy in a modified International Style, and included both a low building with exhibition space and a 26-story office block. The project also included the construction of a housing development directly behind the complex.
The Coliseum was planned by Robert Moses, an urban planner and the chairman of the Triborough Bridge and Tunnel Authority (TBTA). In 1946, it was proposed to build a convention center within a new Madison Square Garden building at Columbus Circle. This plan was not successful, nor was another plan for the Metropolitan Opera House. After years of delays, the Coliseum was approved in 1953, and construction started in 1954. The Coliseum hosted its first exhibits on April 28, 1956, followed by hundreds of conventions over the next four decades. The Coliseum supplanted the Grand Central Palace as the city's main convention center until the 1980s, when the Coliseum was superseded in that role by the Javits Center.
The TBTA's successor, the Metropolitan Transportation Authority (MTA), started looking for buyers in order to raise money for its operations. Boston Properties attempted to negotiate a lease between 1987 and 1994. The site was ultimately bought by a joint venture between Time Warner and The Related Companies in 1998, and the Coliseum was demolished in 2000 to make way for the Time Warner Center.
