Castle Island

Castle Island 
Castle Island is a peninsula in South Boston on the shore of Boston Harbor. In 1928, Castle Island was connected to the mainland by a narrow strip of land and is thus no longer an island.  It has been the site of a fortification since 1634, and is currently a 22-acre recreation site and the location of Fort Independence.
