Fortification Island

This tiny island is located on the shore of Boston Harbor in south Boston and is the site of a 17th-century fortification used as an advance line of defense. The island, though still called such, lost its title of "island" in 1928 when it was connected to the mainland by a narrow strip of land.

Currently, the fortification known as Fort Independence sits on the 22-acre recreation site Castle Island which is open to the public year round. If you're in Boston between Memorial Day weekend and Labor Day you can take a guided tour of Fort Independence on Saturday or Sunday. The fort is also open Thursday nights during the summer until dusk where visitors can walk the ramparts and go back in time to help defend the colonies.
