Fort Independence (Massachusetts) Fort Independence is a granite bastion fort that provided harbor defenses for Boston, Massachusetts. Located on Castle Island, Fort Independence is one of the oldest continuously fortified sites of English origin in the United States. The first primitive fortification, called "The Castle", was placed on the site in 1634 and, after two re-buildings, replaced circa 1692 with a more substantial structure known as Castle William. Re-built after it was abandoned by the British during the American Revolution, Castle William was renamed Fort Adams and then Fort Independence. The existing granite fort was constructed between 1833 and 1851. Today it is preserved as a state park and fires occasional ceremonial salutes. Fort Independence was added to the National Register of Historic Places in 1970.
