The New York World Building was a building in the Civic Center of Manhattan in New York City, United States, along Park Row between Frankfort Street and the Brooklyn Bridge. Part of Lower Manhattan's former "Newspaper Row", it was designed by George B. Post in the Renaissance Revival style, serving as the headquarters of the New York World after its completion in 1890. The New York World Building was the tallest building in New York City upon completion, becoming the first to overtop Trinity Church, and was by some accounts the world's tallest building at the time of its construction.
