The Flatiron District, with its convenient central location, is popular among older business people, young artists and frenzied shoppers alike. Located on the east side, the neighborhood extends from 14th Street to 23rd Street and is bounded by Park Avenue South to the East and 6th Avenue to the West. The district gets its name from the Flatiron building, the first steel-framed building, famous for its triangular shape and also the tallest building in the world in 1903. You can enjoy the sophisticated Restaurant Row on Park Avenue South, large discounters like Filenes' Basement along Sixth Avenue, and classier shopping on Fifth and Broadway. Madison Square Park is a wonderful, renovated spot to walk your dog or just sit on a bench and enjoy the scenery. The Flatiron District has some of the most detailed and beautiful architecture in Manhattan as well and many huge, airy lofts.
