Old Westbury Golf & Country Club

William C. Whitney acquired the 530-acre estate in 1887; it passed through the Whitney family (Harry Payne Whitney, then Cornelius Vanderbilt "Sonny" Whitney) across the early 20th century, with Gloria Vanderbilt living there in the 1930s. In 1942, C.V. Whitney built a new mansion on the property that later became the club's clubhouse, and in 1961 the newly formed Old Westbury Golf & Country Club purchased roughly 200 acres of the estate -- including the mansion, tennis house, polo buildings, stables, and tower -- to found the club.

Old Westbury G&CC is described by the club itself as a premier, member-owned private country club with 27 holes across the property's Woods and Bluegrass nines. No bundled residential development is associated with the club; it is a standalone member-owned institution within the affluent, low-density Incorporated Village of Old Westbury.
