Flatiron Building 175 5th Avenue, New York 710

The Flatiron Building, originally the Fuller Building, is a triangular 22-storey steel-framed building 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 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. The building was designed by Chicago's Daniel Burnham as a vertical Renaissance palazzo with Beaux-Arts styling. The fascia is limestone at the bottom changing to glazed terracotta from the Atlantic Terra Cotta Company in Tottenville, Staten Island as the floors rise.
