The Flatiron Building Under Construction, 1902

The Flatiron Building is probably one of the world's most recognisable 20th century skyscrapers and a landmark of the Big Apple. Originally named the Fuller Building, designed by Daniel Burnham and Frederick Dinkelberg, the 22 storey was at the time of its completion, the tallest building in New York. The unusual triangular plan is formed by Fifth Avenue, Broadway and East 22nd Street, giving it the nickname 'flat iron' due to its resemblance to a cast-iron clothes iron. Construction incredibly took just a single year with a precision steel frame designed to withstand strong winds.

The building's original tenants ranged from publishers to the Imperial Russian Consulate and even a basement jazz club in the basement, introducing New Yorkers to black jazz in the city. In the background of the photograph to the left you can also see 670-674 Broadway, otherwise known as the Brooks Brothers Building, where Abraham Lincoln bought the very suit he would wear on the night of his demise at Ford's Theatre in 1865.
