In the 1950s, Theodore Edison, who summered here for many years, purchased about 300 acres of the undeveloped areas of this small island and formed an organization, Monhegan Associates, which is primarily a land trust, to protect the lands in perpetuity. In the past sixty years Monhegan Associates has acquired more land through gifts and purchases. At this point we own approximately 380 acres of land, comprising about two-thirds of the island. That land is not developed, except for many miles of hiking trails going through it, which are open to the public. Here’s our Mission Statement.
