The Estate is made up of three properties: Castle Hill, a National Historic Landmark, is the home of The Great House, a spectacular venue for weddings and corporate events, guided tours, and programs; Crane Beach, a popular public beach and summer destination; and the Crane Wildlife Refuge, which encompasses several small islands and a vast salt marsh in Essex Bay.
The Trustees preserves, for public use and enjoyment, properties of exceptional scenic, historic, and ecological value in Massachusetts.
