The Flatiron District is a small neighborhood in the New York City borough of Manhattan, named after the Flatiron Building at 23rd Street, Broadway and Fifth Avenue. The boundaries of Manhattan neighborhoods are notoriously hard to pin down and tend to be in flux, but generally the Flatiron District can be said to be bounded by 14th Street, Union Square and Greenwich Village to the south; Sixth Avenue and Chelsea to the west; 28th Street and Midtown South to the north; and Lexington Avenue/Irving Place, Gramercy Park and the neighborhood of Gramercy to the east.
The name Flatiron was given to the area starting 1985, as the area became more residential and restaurants started to boom in the area. Before this time, the area was mostly populated by tourists and photographers, due to the large number of photography studios and advertising agencies in the area. The location is most noted for the Flatiron building, which is one of New York City's oldest skyscrapers. It stood as the tallest building in the world for four years after it was built in 1909.
