The Fens is one of the major neighborhoods of Boston in Fallout 4.


The following section is transcluded from Boston. To modify, please edit the source page.

West of Back bay this neighborhood derived its name from the origin of its pre-War name – Fenway–Kenmore. The Fens, sometimes called Back Bay Fens, was a parkland and urban wild within the heart of Boston, was built in 1870 to serve as a link in the Emerald Necklace park system.[1]

Currently the friendliest neighborhood in all of downtown Boston, The Fens is the home of Diamond City – "the Great, Green Jewel of the Commonwealth." The rest of the neighborhood however is occupied by raiders and slavers.[2]


The Fens is host to many locations, one of which is Hangman's Alley which can be used as a player settlement. Another location is the Fens Street Sewer, last but not least the wreck of the USS Riptide can be seen in the middle of the river.

The Fens also hosts Back Street Apparel, Hardware Town, Parkview Apartments, and finally Police Precinct 8.

  2. Fallout 4 Vault Dweller's Survival Guide Collector's Edition p.428: "Zone 9: Neighborhood: The Fens
    This is perhaps the friendliest neighborhood in all of Boston. The giant green walled-off enclosure welcomes all travelers without ghoulish tendencies, and the threats to your life are manageable if you keep near the huge green walls. Venture farther afield and you may stray into danger: You’ll run into Zone 3 if you keep heading west. Go up to Cambridge if you cross the Charles River, and journey east to Esplanade and Back Bay. South is Zone 6. Most of the outskirts of this neighborhood feature closed-off Raider camps, which have been decimated recently by the even-more carnage-hungry Super Mutants. But you’re here for the trading, the questing, and the camaraderie offered here, in the great green jewel of the Commonwealth."
