Historians agree that bars in Massachusetts are about as old as the state itself. Early settlers wasted no time setting up local taverns before schoolhouses in some cases. In fact, Massachusetts is home to what are believed to be the oldest bars in the United States like the Green Dragon Tavern which dates back to 1654, or Warren Tavern in Charlestown which was the first building to be erected in Charlestown after the British burned the whole town during the Battle of Bunker Hill in June of 1775.
