Charlestown is a historic waterfront neighborhood with Irish-American roots located just across the Charles river from downtown Boston. The Freedom Trail climbs streets lined with brick townhouses and clapboard triple-decker homes to the Bunker Hill Monument, site of a key Revolutionary War battle, the battle of Bunker Hill. The 1797 U.S.S. Constitution warship and its museum are in the Charlestown Navy Yard. Main Street’s traditional pubs and stylish restaurants draw young professionals and families.
