Back Bay is a district in Boston in the Commonwealth in 2287.


Prior to the Great War, Back Bay was known for its significant architecture.[1] Serviced by Copley Station on the Green Line, the district contained the Boston Public Library.

The location was also home to several skyscrapers, such as Trinity Tower, Wilson Atomatoys corporate HQ, and the Dartmouth Professional Building. After the bombs fell, the district was primarily taken over by raiders and super mutants.


Bordering The Fens to the west, Esplanade to the north, and Boston Common and the Theater District to the east, Back Bay contains a variety of locations, including:

    "Back Bay was once known for its numerous brownstones of architectural significance. It is now dominated by the Trinity Tower skyscraper, an immense building constructed close to the old church and public library. Now the streets and alleyways are home to roving bands of Raiders, ferals, and packs of wild dogs. The tower still stands, which is more than can be said for another skyscraper, which has half toppled into the Dartmouth Professional Building. Keep going south to reach a Raider tenement block stronghold of Layton Towers. Super Mutants have a powerful grip on this part of the city, too, decorating the Wilson Atomatoys Corporate HQ and Trinity Tower with meat bags and bloody spikes."
