Dunwich Building is a ruined office building in the Capital Wasteland, located at the southwestern most point on the map, south of Girdershade and far west of Tenpenny Tower. It is a medium sized office building with three interior sections.


Before the war, the building was owned by Dunwich Borers LLC, a company that manufactured rock drills for tunneling and drilling. A locked computer terminal midway through the building contains audio transcripts of a company executive. The transcripts function to both praise the release of a new drill, the sounds of bombs dropping and what appears to be the horrible words of the bombs effects on the workers, by turning them into feral ghouls.



The immediate vicinity of the Dunwich Building is a barren area marked by jagged rocky terrain and steep cliffs. Immediately due west, in line with the north face the building at the base of the cliffs, is a booby-trapped baby carriage accompanied by a dead raider.


The building is a dark set of interior ruins populated by various types of feral ghouls. A number of audio-logs and computer terminals provide visitors with background on the building and an unfortunate wastelander named Jaime. In addition to the building itself, two separate levels lie underneath. The deepest level is a cavern with an eerie obelisk - a woman emerges/reaches out from the obelisk; vines entangle the obelisk and skulls run up its back. It is also rather highly irradiated, reaching up to 20 rads at the top. Several feral ghouls appear to worship it, and although similar, it is not connected with the statue in Underworld.

The building is broken up into three parts: the Dunwich Building Entrance, the Forsaken Dunwich Ruins, and the Virulent Underchambers. The deeper you go into the Dunwich Building the darker it becomes, and eventually the use of the Pip-Boy light is necessary. You can only access these areas in respective order, but there is a shortcut back to the first room from the Virulent Underchambers. Note this is one way only.

When you pass through a certain doorway, early in the Forsaken Dunwich Ruins section, you will have a hallucination to pre-War times and see a man in front of you. You will then come back to reality and see it is a glowing one. In the hallucination, it is possible through a glitch to enter V.A.T.S. and see the name of the pre-War man.

Near the entrance, you find a set of five audio logs left by an unfortunate visitor named Jaime. As you proceed further into the building, you find four additional audio logs documenting his transformation into one of the building's deranged inhabitants. The final audio log found within the building, though mostly rambling by an insane, ghoulified Jaime, mentions the name "Alhazred".

In the Virulent Underchambers, the player can actually discover the creator of the increasingly demented audio logs (who has now fully mutated into a ghoul) and a handful of feral ghouls worshiping the obelisk. As Jaime stands facing the obelisk with arms upraised, it appears that he is somehow summoning ghouls out of the mist-shrouded recess in the rock wall opposite. Interestingly enough, killing Jaime, who is armed with a Chinese assault rifle, counts as a positive Karma act (if the player previously chose the Lawbringer perk, Jaime will also drop a finger), and does not turn the ferals hostile if they weren't. The obelisk in the center is irradiated about half way up, and emits levels of radiation that max out at 20 rads per second. As a side note, once the player crosses the threshold of the doorway into the cave with the obelisk, an "eerie voice" can be heard if the volume is up high enough (along with the "effects" sound setting). You can only access these chambers via the Forsaken Ruins.

There is also a log on a terminal made by an unnamed scavenger who wandered into the ruins, hoping to find it abandoned. Upon finding the ghouls, he holes up in the room with the terminal and as paranoia sets in he remembers his friend "Billy" coming with ammunition and grenades. Using this cheerful optimism he logs off the computer and survives for an unknown period of time. The skeletal remains in front of the computer and the second set of remains just inside the entrance to the Dunwich building, accompanied by a box of ammunition and a box of grenades, seem to suggest that his friend was ambushed and killed shortly after entering the building, and with no extra ammunition or hope of rescue, the scavenger was either overrun or committed suicide.

If you have the Point Lookout add-on, you can burn the Krivbeknih book in the Virulent Underchambers obelisk as an optional part of The Dark Heart of Blackhall quest. (You can also burn the Krivbeknih outside of this quest, although there is no apparent effect other than the item being removed from the inventory).

Notable loot

  • Bobblehead - Melee Weapons located in the Virulent Underchambers, on the ground right at the end of the zone (at the shortcut door leading back to the Dunwich Building).
  • Dean's Electronics located in a side room with cleaning/maintenance supplies in Forsaken Dunwich Ruins. The room is upstairs off the southern hallway at the center of the map (halfway between the Dunwich Building and Virulent Underchambers exits on the map). The book is located to the right of the toolbox on the shelf.
  • Nuka-Cola Quantum located on the ground floor, northeast of the entrance, in a closet at the bottom of the stairs.
  • Jaime's personal journal entries #1-5 on the table to the left when entering the building. Entry #6 is on the same floor, in the western chamber, on a desk with a radio. Entry #7 is on a blood-covered table just outside the door to Forsaken Dunwich Ruins. Entry #8 is on the first level of the Ruins section, in the center of the large chamber where the hallucination takes place, on a desk with the computer terminal (easy) containing dictation records. Entry #9 is on a desk just inside the entrance of the Virulent Underchambers.

Related quests


  • Available supernatural phenomena include:
    • In the Dunwich Building Entrance you will find a "self-opening" door (upper area in the south corridor), but you need to come from the east.
    • The instantaneous flashback happens in the beginning of the Forsaken Dunwich Ruins, after a stair and a left path (the only way to continue this part of the building).
    • Upon entering the room where the unknown adventurer refers to "Billy" a coffee pot is thrown to the floor and a fan on the desk is knocked over.
    • When facing the entrance from the outside, you are facing south. When inside, with your back to the door, you are facing north.
  • Various terminal entries provide a bit of pre-War backstory and stories of other wastelanders who ventured into the building.
  • Ronald Laren from Girdershade can be asked about anything interesting in the area, causing him to tell you to "Stay away from the Dunwich building, that place is bad mojo."
  • When entering the flashback, the walls and ceiling appear to be in bad condition and chipping, which is strange as the flashback is pre-War, before the building was abandoned and deteriorated.
  • A severed head can be found on a table on the first floor of the Dunwich building, just before the Forsaken Ruins. It is placed upright on the table with Jaime's seventh log. However, exiting to Forsaken Ruins and returning causes it to disappear.


Dunwich Building appears only in Fallout 3.

Behind the scenes

  • The story told in the personal logs found in the Dunwich Building, the name of the building, the whispering obelisk found in the Virulent Underchambers, and many other facets of this location refer to H.P. Lovecraft's Cthulhu mythos. See especially The Dunwich Horror.
  • The strange voice near the Obelisk is actually repeating the name "Alhazred", which is also the name Jaime repeated several times in his last audio tape. Sometimes the voice may instead repeat the name "G'yeth", also repeated by Jaime in his last audio tape. In the stories of H.P. Lovecraft, Abdul Alhazred is the author of The Necronomicon.

  • PCIcon pc.png Xbox 360Icon xbox360.png In the mutilation room just prior to the door to the Virulent Underchambers, a head will appear chattering on a desktop. This happens when you access a trap computer terminal on the floor directly above the "chattering head". Upon a secondary explosion (caused by a frag grenade, for example), the "chattering head" will leave the desktop and reveal itself to be a dismembered torso with a head, which had previously clipped on the desk.
  • PCIcon pc.png PlayStation 3Icon ps3.png Xbox 360Icon xbox360.png It is possible that the obelisk will not emit any radiation at all.
  • PCIcon pc.png PlayStation 3Icon ps3.png If you are exiting Dunwich with a companion, he or she will often spawn around the back (south) of the building, where upon they can be attacked. Even if you run back to defend them, it is likely that one or both will be killed. One way of avoiding this is fast traveling right away, though sometimes the radscorpion will travel with you.
  • Xbox 360Icon xbox360.png In the room leading into the Forsaken Dunwich Ruins there will be two heads. One of them is on the desk, and one on the floor. If you grab on to the desk head you can make it look up and down. You can also grab the one on the floor and drag it around the room with you. Note that it will still be stuck in the floor and glide around comically.
  • Xbox 360Icon xbox360.png In the underground chamber, the feral ghoul reavers will still attack even though you are wearing the ghoul mask. Not sure if this is a bug or intentional.
