1221 Avenue of the Americas

1221 Avenue of the Americas (formerly also known as the McGraw-Hill Building) is an international-style skyscraper at 1221 Sixth Avenue (also known as the Avenue of the Americas) in Midtown Manhattan, New York City. The 51-floor structure has a seven-story base and a simple, cuboid massing. The facade has no decoration and consists of red granite piers alternating with glass stripes to underline the tower's verticality. It served as the headquarters of McGraw Hill Financial from 1972 to 2015. The building is set back 115 feet (35 m) from Sixth Avenue. Its sunken courtyard formerly contained Sun Triangle, a 49-foot (15 m) abstract steel sculpture by Athelstan Spilhaus. The tower's lobby is clad in dark red terrazzo and red marble, with aphorisms by Plato and John F. Kennedy.
