The Flatiron Building, originally the Fuller Building is a triangular 22-story 285-foot-tall (86.9 m) steel-framed landmarked building located at 175 Fifth Avenue in the eponymous Flatiron District neighborhood of the borough of Manhattan, New York City. Designed by Daniel Burnham and Frederick Dinkelberg, it was one of the tallest buildings in the city upon its 1902 completion, at 20 floors high and one of only two “skyscrapers” north of 14th Street – the other being the Metropolitan Life Insurance Company Tower, one block east.
