Perhaps the most extraordinary of the "Seven Sisters"-seven estates designed by Stanford White and Frederick Law Olmsted for the ultra-private, turn-of-the-century Montauk Association summer colony-Dick Cavett's 20-acre, bluff-top estate with over 900 feet of ocean frontage and sensational 360-degree views is bordered to the east by over 190 acres of oceanfront parkland that embraces an additional 2,200 feet of pristine coastline. Famous guests include Muhammad Ali, Sir Laurence Olivier, Tennessee Williams, Alec Baldwin, and Woody Allen. The 7,000-square-foot home, meticulously rebuilt by the Cavetts in 1997, embodies an exact replica of the original Stanford White design. The reborn three-story, seven-bedroom Traditional, "a simple country house by the sea" in the words of Cavett's late wife, Carrie Nye, is minutes to the regional airport, Lake Montauk marinas, world class golf, and the renowned amenities of the Hamptons. The estate's setting retains its unspoiled environment envisioned for the site's original design by Olmsted-the landscape architect for New York City's Central Park-and is adorned by a winding path leading down to the oceanfront cove with private sandy beach known by local cognoscenti as Cavett's Cove, many miles of equestrian trails, a secluded fresh-water pond inviting meditation, and swimming pool at the end of a special canopied trail reveling in endless views of the sea.
