The Flatiron Building (originally the Fuller Building) is a 22-story, 307-foot-tall (93.6 m) steel-framed triangular building at 175 Fifth Avenue in the Flatiron District neighborhood of Manhattan in New York City, New York, US. Designed by Daniel Burnham and Frederick P. Dinkelberg, it opened in 1902. The building sits on a triangular block formed by Fifth Avenue, Broadway, and East 22nd Street—where the building's 87-foot (27 m) back end is located—with East 23rd Street grazing the triangle's northern (uptown) peak. The name "Flatiron" derives from its triangular shape, which recalls that of a cast-iron clothes iron.
