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.  As with numerous other wedge-shaped buildings, the name "Flatiron" derives from its resemblance to a cast-iron clothes iron. c. 1920
