After the death of Richard Crane, the estate passed to his wife, Florence. In 1945, the Crane family donated much of their private beach and dunes to The Trustees of Reservations, a private, non-profit land conservation and historic preservation organization, with 112 properties throughout the Commonwealth of Massachusetts. When Florence Crane died in 1949, the rest of the property, including the mansion, was given to The Trustees, who maintain the property to this day and offer tours of the historic mansion seasonally.
