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 visitors and there are no public restrooms on the island.
This island of Boston Harbor Islands National and State Park is privately owned. For more information visit graveslightstation.com.
