“There it is. Pretty impressive, huh? Its real name is Fort Independence, but the Minutemen always just called it the Castle.” — Preston Garvey, during Taking Independence
The Castle, also known as Fort Independence, is a location and potential settlement in the South Boston neighborhood of Boston in 2287.
Background The Castle, originally known as Fort Independence, is a historic landmark in the Boston area, dating back to the pre-Revolutionary period. The granite star fort was one of the first forts in the United States, and provided harbor defenses for the city of Boston. Since the Great War, the name of Fort Independence has fallen out of favor, as most residents of the Commonwealth refer to it simply as the Castle.
It served as the headquarters for the Commonwealth Minutemen until 2240, when the Castle was partly destroyed by a gigantic mirelurk queen, and most of the Minutemen leadership wiped out. Their general at the time, McGann, was cut off from the battle early on when the tunnel to his quarters collapsed. While waiting for rescue, he secured the armory by activating its security. Eventually, as he ran out of supplies (and conceded that help was not coming), he drank wine he found, easing his passing into oblivion.
Rebirth Almost fifty years later, the Commonwealth Minutemen under the Sole Survivor (as general) can retake the fort by wiping out the mirelurks that have since made it their nest. They can clear out the egg clutches and corpses and reactivate their communications equipment, returning a critical asset to Minutemen hands. Once this is done, Ronnie Shaw, an older member from before the Castle's loss, calls the general back to open its west bastion and access its armory, giving the Minutemen access to their artillery once more.
