The Flatiron Building (or Fuller Building) Editorial Photo

The Flatiron Building (or Fuller Building, as it was originally called) is located at 175 Fifth Avenue in the borough of Manhattan, New York City and is considered to be a groundbreaking skyscraper. Upon completion in 1902, it was one of the tallest buildings in the city and one of only two skyscrapers north of 14th Street – the other being the Metropolitan Life Insurance Company Tower, one block east. The building sits on a triangular island-block formed by Fifth Avenue, Broadway and East 22nd Street, with 23rd Street grazing the triangle's northern (uptown) peak. As with numerous other wedge-shaped buildings, the name Flatiron derives from its resemblance to a cast-iron clothes iron. The building anchors the south (downtown) end of Madison Square and the north (uptown) end of the Ladies' Mile Historic District. The neighborhood around it is called the Flatiron District after its signature building, which has become an icon of New York City. The building was designated a New York City landmark in 1966, was added to the National Register of Historic Places in 1979, and designated a National Historic Landmark in 1989. The Flatiron Building was designed by Chicago's Daniel Burnham as a vertical Renaissance palazzo with Beaux-Arts styling. Unlike New York's early skyscrapers, which took the form of towers arising from a lower, blockier mass, such as the contemporary Singer Building (1902–1908), the Flatiron Building epitomizes the Chicago school conception: like a classical Greek column, its facade – limestone at the bottom changing to glazed terra-cotta from the Atlantic Terra Cotta Company in Tottenville, Staten Island as the floors rise– is divided into a base, shaft and capital. As an icon of New York City, the Flatiron Building is a popular spot for tourist photographs, but it is also a functioning office building which is currently the headquarters of publishing companies held by Verlagsgruppe Georg von Holtzbrinck of Stuttgart, Germany, under the umbrella name of Macmillan, including St. Martin's Press, Tor/Forge, Picador and Henry Holt and Company.
