The Graves

This rocky ledge is home to the outermost lighthouse in Boston Harbor.

---

 

This bedrock outcropping is one of the Brewsters, a group of the outermost islands in the park. It is an active Coast Guard navigational aid facility, so the buildings are not open to the casual visitor and there are no public rest rooms on the island.

 

Short History
The tallest of the three lighthouses in Boston Harbor, the Graves is sited at the main entrance to Boston Harbor, and continues its tradition as a navigational aid, though now automated.

The Graves Light is listed in the National Register of Historic Places. For more information about the facility, please go to the National Park Service Maritime Heritage Program Inventory of Historic Light Stations.
