William Sloane House, Federal mansion in Upper East Side, Manhattan, United States
The William Sloane House at 686 Park Avenue is a Federal-style residence featuring balanced proportions, classical details, and symmetrical window arrangements across five floors. The facade displays refined decorative elements characteristic of this architectural approach.
The building was constructed between 1916 and 1919 by architects Delano & Aldrich as a residence for industrialist William Sloane and his wife Frances Crocker Sloane. It was built during a period when the Upper East Side became the preferred residential area for Manhattan's wealthy families.
The building now houses the Italian Cultural Institute of New York, which organizes exhibitions, language classes, and cultural events that bring Italian traditions to Manhattan. Visitors can experience Italian art and heritage within these refined historic spaces.
The house is located between East 68th and 69th Streets near Central Park and is well served by public transit at the 68th Street subway station. The neighborhood is walkable and offers easy access to other historic buildings and green spaces nearby.
The property is part of the Park Avenue Houses ensemble, a collection of buildings recognized on the National Register of Historic Places. Together, these residences form a remarkable group of early twentieth-century classical architecture along a single avenue.
