The Pitt ( city ) The Pitt is a city built on the remains of Pittsburgh , Pennsylvania on the East Coast in 2277 . Background . The Pitt was once the city of Pittsburgh , Pennsylvania . Following the Great War , survivors established a settlement on the remains of the city center ( Downtown ) at the confluence of rivers . The rivers seemed to provide a clear resource , and enough of the city was cleared by the bombs that a new settlement could be established . However , radioactive material and unidentified mutagens mixed into the groundwater , causing it to become slightly mutagenic and highly carcinogenic . As a result , the people in the new settlement began to change gradually over time . The changes were subtle , not nearly to the degree of the super mutant s or the various Wasteland creatures , but over the next 140 years , their effects became visible . Starting from the first few years , children were often born with strange growths or extra limbs . The mutations never went far beyond the occasional hunchback or cleft palate , but it wasn ’ t long before the vast majority of the residents of The Pitt developed some sort of physical deformity in their lifetimes . Although many children were born " clean , " the older they became , the more likely it was that a mutagenic problem would manifest as they developed . The most disturbing change that the environment caused was not nearly as noticeable as the physical deformities . The infected water and poisoned sky began to cause neurological damage to those exposed to it . People became more hostile , violent , and short - tempered ; they became known as " Wildmen . " Their emotions began to run out of control , often teetering on primal . In severe cases , mutated humans devolved into hunched , savage beasts nicknamed " trog s . " Over the first 50 years , The Pitt quickly degenerated into a dangerous urban jungle ; even cannibalism was not uncommon . Rumors of the horrors of The Pitt spread throughout the Wasteland , and all travelers knew to avoid it at all costs . However , The Pitt became one of the most self - sufficient communities in the Wastes . Although their self - sufficiency relied on the citizens occasionally eating one another , they nonetheless functioned without trade or export . In 2255 , Star Paladin Lyons of the Brotherhood of Steel led the Scourge , a large - scale military action that wiped out nearly the entire population of The Pitt . In a single night , the Brotherhood swept through the city , eliminating any resident who put up a fight . Although the intent of the Scourge remains unclear , several unmutated children were taken from The Pitt by the Brotherhood and placed into initiate training . The motivations for the Scourge are unclear to this day , but many in the Brotherhood note that it was a marked change in the way the Brotherhood operated . Additionally , it is known that something was recovered from The Pitt during the Scourge , although to date it would seem that only Elder Lyons knows what it was . It is said that one man - a Brotherhood of Steel Paladin from the Scourge - stayed on in The Pitt , seeking to bring law and order to the unwashed masses and creating an underclass of slaves in the process , guarded by raiders under his personal command . However , in the decades following the events of the Scourge , nobody has heard anything from The Pitt . Travelers who have gone to investigate have not returned , and no survivors have emerged . Layout . Train yard . The main trainyard for The Pitt has long since fallen into disrepair , and the main rail bridge into the city has fallen into the highly toxic river . In addition , the tunnel is blocked , preventing further journey on rails . A small scouting party of Pitt raiders guards this yard , ready to report back to the main gate if any enemies are spotted or if slaves try to escape . This is moderately well guarded and is the last stop between the Wasteland and The Pitt . Bridge . Despite ruling The Pitt with an iron fist , there are still pockets of resistance throughout the city , not least of which is an old Slave Trading Post near the Wabash Bridge , which is now under the control of Wild Men . The bridge is a dangerous trap - filled pathway with vicious dog s and a sniper , but it ' s better to face these than dive into the river below , as radioactive death is instantaneous . On the north side of the bridge , slaves periodically attempt to flee and are blown apart by the many scattered mine traps . Down the street is the main gate to Downtown , guarded by the ever - offensive Mex and his lackeys . Downtown . Home to the majority of the slaves working in the nearby Mill , Pitt Downtown is a gruesome , grimy , and desperate place , where Pitt raiders rule and slaves are treated worse than dogs . From the main courtyard , with a hole and a furnace , there ' s an alley leading northeast toward a ' Market Square ' , where the majority of the slaves plot rebellion . Above the ground , and accessed only after victories in the Arena , are the upper scaffold pathways and bridges . These are home to Pitt raiders , who can keep constant vigil on their property down below . Steelyard . Once the main Steel - producing center of The Pitt , recent and increased activity by Wild Men and trogs have rendered this a largely - uninhabitable area . Slaves unlucky enough to be ordered to work in this gloomy location are usually killed or eaten ( or both ) by the inhuman trog s and Wildmen that prowl this grimy area , or fall to their deaths from one of the many decaying catwalks and balconies . Uptown . Uptown is primarily a Pitt raider paradise , with defenses and lighting constantly checked to ensure no trog incursions occur . Part of the crumbling tenement blocks hold a number of wandering raiders , all loyal to Ashur . Much like Downtown , you are able to access the ground and upper levels via a series of scaffolds and catwalks . North of the open - plan tenements is an Abandoned Apartment . To the east is the main Courtyard and the entrance to the power plant and Haven interior . Haven . Dominating this expansive courtyard plaza is a giant effigy , flanked by two bouts of intermittent ﬁre . A twisted monument to the sickness , this has the added benefit of keeping trogs away , as they are light - sensitive . However , Ashur knows from past massacres that the lights must be kept on to avoid a trog influx . The effigy stands at the foot of Ashur ’ s base . It is a skyscraper known as Haven , due to the safety and experimentation into curing the sickness that takes place inside . Appearances . The Pitt appears only in the " Fallout 3 " add - on " The Pitt " , and is mentioned in " Fallout 3 " Point Lookout . Bugs . Upon first return from The Pitt , the player ' s Pip - Boy may still have an " orange outline " on it , this will be fixed if the player restarts the game .
