National Monument · NY

Located at the southern tip of Manhattan, Castle Clinton marks the place where New York City began and reflects the growth of both the city and the nation. Built to defend the harbor during the War of 1812, it has since welcomed theatergoers, immigrants, and sightseers—and today continues to greet millions of visitors to New York Harbor.
