A piece of Kennedy family history could be yours for $35 million.

Jean Kennedy Smith, the longest surviving sibling of late president John F. Kennedy, is selling her Hamptons estate.

The lavish estate is comprised of two separate properties on the famed Sagaponack Road in Bridgehampton.

According to the New York Post, the asking price of $35 millions represents both a $20 million waterfront home and a $15 million cottage with a pool. As per 27east.com, these parcels can be bought separately.

The main 6,000 square foot house boasts nine bedrooms and six bathrooms, a dock, a pool, a tennis court, and almost five acres of surrounding land. Meanwhile the four-bedroom cottage is described as a "ranch home".
