The entrance is located directly south of Faneuil Hall, past a door with an Advanced lock on the south side of the building leading to a door or through a gap in the wall to the elevator. Both guarded by two raiders and one turret. It is also possible to gain entry from the south side through a gap in the fence and an unlocked door. There are two accessible floors to this building and the roof.
The first floor is just a stairwell. At the top of the stairwell on the third floor is a locked (Advanced) restroom with a First Aid box.
The third floor contains two terminals. One (Easy) gives access to a police protectron. Behind the counter in a small vestibule is the other (Expert) terminal that controls the main bank vault. In the small office opposite the protectron is a (Novice) safe.
The Commonwealth Bank only appears in Fallout 4.
