Scene was shot The southern shore of Manhattan has been known as The Battery as far back as the 17th century when it housed the guns that protected Manhattan from attacks by sea. The remaining west battery, known as Castle Clinton and built just before the Ware of 1812, was originally constructed on a small island off the shore and eventually the land expanded and encircled the fort in 1855. The modern park now occupies 25-acres and features a small far, restaurant, carousel, and WWII memorial.
