1221 Avenue of the Americas

1221 Avenue of the Americas is an international-style skyscraper located at 1221 Sixth Avenue, in Midtown Manhattan, New York City. The 51-floor structure has a seven-storey base and a simple, cuboid massing. The intentionally featureless facade offers no decoration and consists of red granite piers alternating with glass stripes to underline the tower's verticality. There is a 35-meter setback from Sixth Avenue, featuring a sunken courtyard dominated by the 15-meter abstract steel sculpture named Sun Triangle by Athelstan Spilhaus. The tower's lobby is clad in dark red terrazzo and red marble, and is also decorated with aphorisms by Plato and John F. Kennedy.
The building was part of the later Rockefeller Center expansion dubbed the "XYZ Buildings". Their plans were first drawn in 1963 by the Rockefeller family's architect, Wallace Harrison, of the architectural firm Harrison & Abramovitz. Their letters correspond to their height. 1251 Avenue of the Americas is the "X" Building as it is the tallest at 750 ft and 54 stories, and was the first completed, in 1971. The "Y" is 1221 Avenue of the Americas, which was the second tower completed and is the second in height . The "Z" Building, the shortest and the youngest, is 1211 Avenue of the Americas with 45 stories . It is the 80th tallest building in New York.
