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.
Weathervane: Commonwealth Bank - The vantage point for MILA can be reached by using the right hand side elevator to reach the top floor. It is also possible to jump from the bow of the USS Constitution if the ship has relocated to its new position after completing the associated missions. The jump will require power armor equipped with the jetpack mod.
The Commonwealth Bank only appears in Fallout 4.
