The history and bricklaid beauty of Boston is easy to enjoy. Follow the Freedom Trail past Old North Church, Paul Revere Park, Fanieul Hall, the Commons, Old Ironsides and more landmarks of America's birth. Across the Charles River is Cambridge and Harvard. Venture to Marblehead and Salem to the south, or Lexington and Concord to the north. Back in town, have clam chowder at the warf or great Italian food in North End.
