|For the Fallout 76 location, see Charleston.|
North of the Charles River, Charlestown is the oldest of the Boston neighborhoods. It was the location of the Battle of Bunker Hill in the American Revolutionary War and is home to historical relics such as Bunker Hill and the USS Constitution. The area was also home to the regional office of the BADTFL, a federal agency involved in the investigation of crime boss Eddie Winter and his associates.
In the abandoned house in Charlestown, holotapes can be found describing how Research Assistant Peters underwent voluntary exposure to radiation in order to test out an experimental radiation treatment serum.
Charlestown appears only in Fallout 4.
