The Flatiron Building, or Fuller Building as it was originally called, is located at 175 Fifth Avenue in the borough of Manhattan, and is considered to be one of the first skyscrapers ever built. Upon completion in 1902 it was one of the tallest buildings in New York City. The building sits on a triangular island block at 23rd Street, Fifth Avenue, and Broadway, anchoring the south (downtown) end of Madison Square. The neighborhood around the building is called the Flatiron District after its signature building, which has become an icon of New York.
Today, the Flatiron Building is frequently seen on television commercials and documentaries as an easily recognizable symbol of the city, shown, for instance, in the opening credits of The Late Show With David Letterman or in scenes of New York City that are shown during scene transitions in the show "Friends".
