One Astor Plaza is a 745 ft (227 m) high skyscraper in Times Square in Midtown Manhattan, New York City. Completed in 1972, the building is 54 stories tall and was designed by Der Scutt of Ely J. Kahn & Jacobs. It is located at 1515 Broadway between West 44th and 45th Streets and is currently the headquarters for Viacom and houses the MTV Studios, Minskoff Theatre, PlayStation Theater, and some retail outlets. The Hotel Astor had occupied the site from 1904 to 1967. Construction of the building began in 1968 and was completed in 1972. The building was the headquarters of the now-defunct W. T. Grant retail chain, which leased almost 400,000 square feet (37,000 m2) of space on the building's top 14 floors.
