The Metropolitan Life Insurance Company Tower (colloquially known as the Met Life Tower and also as the South Building), is a skyscraper occupying a full block in the Flatiron District of Manhattan in New York City. The building is composed of two sections: a tower at the northwest corner of the block, at Madison Avenue and 24th Street, and a shorter east wing occupying the remainder of the block bounded by Madison Avenue, Park Avenue South, 23rd Street, and 24th Street. The South Building, along with the North Building directly across 24th Street, comprises the Metropolitan Home Office Complex, which originally served as the headquarters of the Metropolitan Life Insurance Company (now publicly known as MetLife).
