Breuer Building, 945 Madison Avenue

Marcel Breuer, 1966. Built for the Whitney Museum of American Art on the corner of Madison Avenue and East 75th Street, the building steps outward as it rises, so each floor overhangs the one below like an upside-down staircase, and a large trapezoidal window juts from the dark granite like an eye. A walled moat and a bridge separate it from the sidewalk. This 2019 photo shows it during its years as the Met Breuer. After the Whitney moved downtown it served the Met and then the Frick, and since November 2025 it has been Sotheby's headquarters, restored by Herzog & de Meuron.
