The Ukranian Institute occupies one of the grandest turn-of-the-century town houses that remain in New York City, the Fletcher-Sinclair Mansion, designed by famed, Gilded-Age architect C.P.H. Gilbert in his signature French-Gothic Style. The mansion is located on the southern tip of Museum Mile diagonally across from the Metropolitan Museum of Art, on the southeast corner of 79th Street and Fifth Avenue. It stands as a gem among New York City's mansions.
