399 Park Avenue is a 41-story office building that occupies the entire block between Park Avenue and Lexington Avenue and 53rd Street and 54th Street in Midtown Manhattan, New York City. The building was the world headquarters of Citigroup from 1961, when it moved from 55 Wall Street, until 2015, when the company moved to 388 Greenwich Street.[1]
History
The building lot was assembled by Vincent Astor who initially planned to build a 46-story Astor Plaza on the site. Astor had problems completing the assembly of the lots of mostly residential buildings as a pharmacy held out. In 1974, the company opened the Citigroup Center annex across Lexington to the east. In 1987, Citigroup sold one third of its interest in the building along with two-thirds of its interest in Citigroup Center to Dai-Ichi Mutual Life Insurance Company for $670 million. At the time, Citigroup said it was moving many of its offices to One Court Square
