The island got its name from the fact that every fort located here was always informally known as "The Castle."

After the evacuating British destroyed the islandÌs fortifications 1776, the fort was repaired by troops under the command of Lt. Paul Revere. The present five pointed granite structure is the eighth fort to occupy this site and contains over 172,687 linear feet of hammered stone and was constructed under the direction of Colonel Sylvanus Thayer between 1834 and 1851. and. Many people erroneously believe Fort Independence to be constructed with granite from nearby Quincy; however, with local stone being more costly, the project was instead carried out at considerable savings to taxpayers with granite hauled by boat from quarries on distant Cape Ann.

On October 15, 1970, Castle Island and Fort Independence were placed on the Register of National Historic Places.
