Charlestown hosts Massport properties that include the Boston Auto Port, the Mystic and Medford Street Maritime Terminals and Constitution Marina Office Park.

Charlestown was the first capital of the Massachusetts Bay Colony and is perhaps best known as the site of the American Revolutionary War Battle of Bunker Hill that took place on June 17, 1775. 

Charlestown is also home to several other places of historical interest including the USS Constitution, oldest commissioned vessel in the US Navy; the Charlestown Navy Yard which once employed more than 47,000 workers during World War II and was built on the site where Paul Revere began his famous "midnight ride" to warn minutemen at Lexington and Concord the British were coming; as well as the Warren Tavern, favorite gathering place of Revere and other Boston patriots, that remains in business today.
