A city of history and tradition, Boston offers a proud legacy of culture, education, and numerous sporting championships. The "shining city on a hill"s independent spirit has been displayed to the world ever since colonists were angry over a British tax on their beloved tea and dumped shiploads of it into the harbor in protest.
