The Goldthwait Reservation is a private, non-profit land trust created in 1947 by Dr. Joel Goldthwait to preserve and maintain the natural setting of approximately 12 acres, comprised of Goldthwait Beach, the surrounding land area and salt marsh. At the time, Dr. Goldthwait was being urged to sell this land as parcels for development. The Reservation was his response. The Goldthwait Reservation is for the use of Marblehad residents only.
