Diamond City

Diamond City, also referred to as the "Great Green Jewel," is a large fortified settlement in the Fens neighborhood of Boston in 2287.

The settlement was built within Boston's world-renowned baseball stadium, which once hosted Boston's resident "swatting sultans". Its distinctive green color is visible on the tall, reinforced walls, earning the left-field wall nickname the "Green Monster."

With its own police force, public school, robust agriculture and industry, and a great deal of economic influence across the region, it is by far the most prosperous settlement in the Commonwealth. Diamond City Radio is a symbol of its prosperity and might.

Background
With the years of pre-War baseball long past, Diamond City was founded in the stadium's stead. The settlement established itself as a safe haven for settlers of the Commonwealth, thanks to what its residents affectionately referred to as "the Wall." Later decades saw Diamond City grow into the Commonwealth's largest and most prosperous community. It developed a degree of social stratification, as wealthier residents came to occupy properties in the settlement's exclusive upper stands. These overlooked the lower field, where those with less means took up residence.

Post-War events
The stadium and its residents have experienced several significant events since the War. In 2180, the Commonwealth Minutemen defended the city from an attacking horde of super mutants, causing the militia's rise to prominence. The Broken Mask incident that occurred fifty years later, in 2229, had a far more lasting impact. A visitor named Mr. Carter suddenly opened fire at a centrally located Diamond City bar, killing several citizens. After Diamond City security took him down, an examination of his remains revealed that he was a synth. This single incident planted seeds of fear that eventually blossomed into full-scale paranoia about the Institute and its abductions. Since the event, the fear has only escalated due to regular and unexplained disappearances that have persisted for over half a century.

The city continued to grow despite these troubles, affecting the Commonwealth in many ways. One of its more dubious contributions is Goodneighbor, a settlement founded in 2240 by a group of criminals banished from the city, who quickly turned the new town into a haven for activities frowned upon in Diamond City. In 2272, a new restaurant named Power Noodles was established in the city market, with a Protectron known as Takahashi at the helm. The restaurant rapidly became a staple of Diamond City culture. Piper Wright and her sister Nat also immigrated to the city to found Publick Occurrences, a newspaper dedicated to changing the city for the better. Her activism has galvanized support for fixing the city's problems, such as corruption among the Diamond City security officers, poorly maintained infrastructure, and lack of maintenance on the Wall separating the city from the wasteland.

However, the city's denizens were not immune to the baser instincts of humanity. In 2282, Diamond City fell prey to a surge of anti-ghoul sentiment, fanned by mayoral candidate McDonough and his anti-ghoul Mankind for McDonough platform. He won the election thanks to the votes of the upper stands citizens, and issued the anti-ghoul decree of 2282 in his inaugural speech. The resulting pogrom was carried out by people the ghouls once called their neighbors, and saw entire families thrown out of the city into the surrounding ruins to perish. The ghouls' abandoned belongings were confiscated by the remaining humans, pacifying the poorer residents of the field.The Sole Survivor: "Thanks. You're not so bad yourself." Hancock: "I never get many complaints. It's just real rare these days, find someone who's not just willing to take things the way they're handed to them. Too many good folks not willing to get their hands dirty and too many assholes taking advantage of it. Look at what happened to Diamond City. Before McDonough took over, it was a half-decent place to live. A little stricter than I usually go for, but not terrible. I thought he and I had a pretty happy childhood. But then he decides he's gonna try and get elected with his anti-Ghoul crusade - "Mankind for McDonough." Before ya know it, you got families with kids lining up to drag folks they called "neighbor" out of their homes and throw 'em to the ruins." The Sole Survivor: "How could they do something like that?" Hancock: "There'd always been a pretty big gulf between the folks living in the stands and folks down on the field. McDonough ran on it because he thought enough of those Upper Stands assholes would vote for him. Guess he was right." The Sole Survivor: "It could have gone worse. At least they left with their lives." Hancock: ''"And how long do you think those folks lasted in the ruins? The city condemned those Ghouls to die. Cowards just got someone else to pull the trigger. I remember storming into his office above the stands after the inauguration speech. He was just standing there, staring out the window, watching as the city turned on the Ghouls. He didn't even look at me, just said: "I did it, John. It's finally mine." Should have killed him right there, but I don't think it would have changed anything. Instead I pleaded with him, begged him to call it off. He said he couldn't. He had nothing against the Ghouls. He was just carrying out the will of the people. And he couldn't betray the voters. And then he smiled. That hideous, fucking mile-long smile. He never smiled like that when we were kids. I didn't even recognize him."'' (Hancock's dialogue) Five years later, in 2287, McDonough remains in power, posing as the city's defender while secretly ensuring the city does not interfere with the Institute's plans. As an infiltrator, he is very capable in his role, although his cover is starting to fray at the edges. Some residents have come to believe McDonough has been replaced by a synth, a suspicion spread by Piper and Nat as part of their investigative journalism.

Society
Diamond City is divided between people living on the former baseball field and those residing in the upper stands. The former comprise the city's laborers, craftsmen, farmers, and other workers, while the latter are caravan owners, merchants, and other individuals who control the lion's share of the city's wealth. McDonough exploited this divide and favored the city's elite, who may have wanted the ghouls gone merely to improve their view.

Diamond City is the only settlement in the Commonwealth that guarantees a free education to all children, regardless of their social or financial status. It also hosts a non-denominational chapel open to all religious adherents, giving them a quiet, safe space to pray and worship. Power is provided by a fusion generator tower in the heart of the city's market, giving its denizens access to cheap electricity.Fallout 4 Vault Dweller's Survival Guide Collector's Edition p.433-438: "[9.08] DIAMOND CITY MARKET This is the most well-known, well-defended settlement in the entire Commonwealth. Located in the remains of Boston’s revered baseball stadium, the city houses several businesses and scores of people in divergent social classes. Every resident shares a common bond; they survived under the shadow of the great green wall—that monument to the ingenuity of humankind and their consummate protector. [01] All Faiths Chapel A multidenominational church open 24 hours a day, run by the friendly Pastor Clements. Sit on a pew in the church to gain benefits of the Quiet Reflection perk. [02] Publick Occurrences ''This location is named after the newspaper, which is written, edited, and published by Piper. Her little sister Nat sells copies at the front of their office. She also publishes stories, such as “The Synthetic Truth,” and is currently on the outs with the mayor. Inside the office, you can read her terminal notes and steal some chems and ammo.'' [04] Fallon’s Basement ''This premiere (and only) clothing store sells a variety of prewar attire at the best prices, as well as helpful outfits, like hazmat suits. The proprietor Becky Fallon tells everyone she’s a direct descendant of the original Fallon family. Aside from a large supply of cram, the only item of note is a Holotape you can listen to regarding the Railroad.'' [05] Power Noodles ''This noodle bar was built up against the fusion generator tower in the center of the settlement, where the pitcher’s mound was. The Protectron chef, Takahashi, has a single phrase—“Nan-ni shimasho-ka?” or “What would you like to have?”—and a single item to trade. Noodles, naturally.'' [10] Swatters ''“A swatter never runs out of bullets!” as Moe Cronin is fond of saying. He runs this store specializing in baseball equipment and almost nothing else. Barter with Moe to obtain a unique bat, and speak to him for a couple of quests that can net you some Caps.'' [13] Chem-I-Care ''This is a popular establishment, thanks to the genial owner, Solomon. Selling a complete variety of chems and healing supplies, Solomon may have convinced the populace that the benefits of his wares outweigh the risks. Pick the lock of his house (Novice) for a few more chems to steal inside.'' [14] Mega Surgery ''Despite the corrugated roof, this is a state-of-the-art medical facility offering healing, cybernetic grafts, and even facial reconstruction. Fancy a change in appearance? Sit down under Doctor Sun’s scalpel! There are some other goings on here too; check the listed side quest before descending into the surgery cellar (Advanced).'' [15] Choice Chops ''Fresh Brahmin meat is available from the sullen butcher, Polly (who’s a frustrated poet), or Mole Rat meat if you’re feeling adventurous. You can break into Polly’s house (Novice) if you want to hack her terminal (Novice).'' [18] The Wall ''The great green wall has protected Diamond City for as long as anyone can remember. Only Abbot spends time here keeping the stage from falling into disrepair, the Brahmins fed, and the wall painted.'' '[22] Science! Center' ''The foremost center of scientific experimentation and discovery in Diamond City, run by the enthusiastic Doctor Duff. Her colleague is a little tired of Duff’s prattling. Take a quiz with Duff if you want. Snoop on Scara’s terminal (Master) if you can.'' [27] Dugout Inn ''This is the primary watering hole of Diamond City. Many of the residents go here in the evenings to grab a drink. Occasionally, the place has guests who are traveling through the Commonwealth, as there are rooms available (and mattresses to sleep on) for 100 Caps. Though the Russian twins who run this place are identical in their features, their personalities are completely different.'' [30] Colonial Taphouse ''The snobbish denizens of the upper area sip their alcohol from this establishment. Receive a dressing down from Wellington in the exterior seating area, then head inside for a pint and a punch if you’re not careful. Look for the Holotape and a floor safe (Advanced) behind the bar.'' [32] Codman Residence ''Break in through the door (Advanced) to the home of the oldest family in Diamond City. The Codmans own the orchard."'' (Fallout 4 Vault Dweller's Survival Guide Map) The irony of nuclear power first destroying the world and then giving Diamond City its main advantage is not lost on the more scientifically-inclined members of the community.

Food is provided to the city by independent farms across the Commonwealth, such as Abernathy farm. However, a much larger supplier is the Codman family, who own both the orchard within the walls and the Codman family farms, which provide brahmin meat to Choice Chops.

Layout
The city is split into social classes, with the rich and powerful residing in the upper stands, and the common people, both housed and unhoused, living in the field below. The center of the city is the market, which is approached by the main entrance stairs from the southwest. Surrounding the market are four main streets laid out along the old baselines: First Street to the south, Second Street to the east, Third Street to the north, and Home Street to the west. The poorest residents sleep under shelters in the area north of Third Street, where they tend a small number of crops (consisting of mutfruit and tato plants). The northern section of the city beyond these shelters features an outdoor auditorium, a brahmin pen, and a much larger crop field. There is also a small irradiated lake to the east of Second Street, where the city's water is purified and sold.

Food can be harvested from the small and large crop fields or the greenhouse, or bought from vendors. Purified water can only be obtained from vendors. All standard crafting stations are available for use in the market. A bed may be rented at the Dugout Inn, or permanently obtained by gaining access to either Home Plate or Kellogg's house.

Appearances
Diamond City only appears in Fallout 4, and is mentioned in Zoe's diary in the Automatron add-on and by Lizzie Wyath in the Nuka-World add-on. It is also mentioned in a question in the Fallout Shelter weekly quest Game Show Gauntlet.

Behind the scenes

 * Diamond City is modeled on the real-world Fenway Park. For example, the Wall is based on the real-world location of "the Wall" or the "Green Monster," popular nicknames for the 37-foot (11.33-meter) left-field wall at Fenway Park. In the real-world Fenway Park, there is also a large Coca-Cola sign approximately in the same location and style as the Nuka-Cola sign in the game. Likewise, the Mass Fusion billboard mounted on a building behind the Wall mirrors the placement of a large real-world advertisement for the Citgo gasoline company made of neon lights. The real sign was rigged so that it could light up the letters C, IT, and GO in sequence ("See it go") when a home run was hit. Finally, there is a single red seat in the northeast bleachers near the GNN sign, representing the "Lone Red Seat" where Ted Williams hit the farthest ball in Fenway Park history in 1946, 502 feet from home plate.
 * Nathan Purkeypile designed much of Diamond City's layout, lighting, and cluttering. It was the first location he worked on for the game, as the developers knew from the beginning that they wanted iconic stadium lights, and that the main quest would point towards the stadium as a "beacon" or landmark that could help the player navigate the Boston area.
 * Atop the press box serving as the mayor's office above the main entrance are five red flags reading "World Series Champions" with the years 1903, 1912, 1915, 1916, and 1918. Banners displaying these years also hang from the stands at intervals on the south and west sides of the stadium. In the Fallout universe, the team never won the World Series again after 1918, and the Curse of the Bambino was never broken. In the real world, the Red Sox finally won the World Series after an 86-year drought in 2004.
 * According to numbers displayed on the bleachers below the Nuka-Cola sign, the team's retired numbers in the Fallout universe were 1, 4, 6, 11, 13, 21, and 33. Of these, 1, 4, and 6 are actual retired numbers. Diamond City resident Moe Cronin's name is almost identical to that of the former real-world Red Sox player Joe Cronin, owner of retired number 4.

Bugs

 * Sometimes, when using the exterior lift from the mayor's office, then activating the second button before the elevator reaches the bottom, the guard rail will extend as if the player were to disembark, then retract upon arrival as if the player is still riding the elevator. Activating the elevator and leaving Diamond City, or entering a building before the elevator stops moving and reloading the game, may fix this.
 * Sometimes, when using the elevator to the mayor's office with a companion, the companion may be transported to the green trash can at the base of the main entrance stairs in Diamond City, and become stuck there. Walking outside of Diamond City to the Fens (manually, without fast-travel) will sometimes free the companion in this situation. Using the console command after selecting the companion's refID can also rectify this issue.
 * Any items placed in the mailboxes, including the one in front of the Sole Survivor's Home Plate residence, will be displayed as owned. Stealing will then be the only way to access the items.
 * After completing the quest Unlikely Valentine, two Triggermen may spawn in Diamond City each time you travel to the city. Most of the civilians in Diamond City will attack the mobsters. There is currently no fix for this issue.
