The Great, Green Jewel of the Commonwealth
Diamond City concept art
Diamond City has stood united for over 150 years. And what keeps us united are two things. First, is the great green guardian behind me. The Wall. Our protector and our savior from the filth of the outside. And second, is our faith and trust in each other. The faith and trust that has given us prosperity, security, and education for every citizen.”— Mayor McDonough, Fallout 4
Diamond City (the "Great Green Jewel" of the Commonwealth), is the largest and most secure settlement of the region in 2287, with its own military force, public school, robust agriculture and industry, and a great deal of economic influence across the Commonwealth. Diamond City Radio is a symbol of its prosperity and might.
Built into the ruins of Fenway Park stadium in the mid 2130s, Diamond City greatly benefited from its central location and the natural protection afforded by the baseball stadium, gradually rising to the position of the Great, Green Jewel of the Commonwealth and becoming an integral part of the region's history and its many factions. Such was the case when the Commonwealth Minutemen rose to prominence after defending the City from a super mutant attack in 2180.
It would also become the source of many of the problems plaguing the Commonwealth. The most notable of those is the synth panic that started with the Broken Mask Incident of 2229, when a malfunctioning third generation synth killed a number of innocent bystanders and was revealed to be a human replica. The resulting fear of the Institute and its machinations would persist even sixty years after the fact. The destruction of the Commonwealth Provisional Government in subsequent decades would also contribute to this paranoia.
Another notable contribution of the city to the region is Goodneighbor. The settlement was founded by a group of criminals banished from the city in 2240, quickly turning it into a haven for all activities that Diamond City would frown upon.
In recent years, Diamond City was gripped by a wave of racism directed at ghouls. A candidate by the name of McDonough ran for the city's mayor on the Mankind for McDonough platform, which was effectively an anti-ghoul crusade. He won the 2282 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 belongings left behind by the ghouls were taken by the remaining humans, enriching the denizens of the field and pacifying them.
Since then, Diamond City continued to prosper. McDonough's stance on the ghouls won him popularity among the Stands and the field, with only Piper Wright and her articles remaining a thorn in his side. McDonough has also taken a hard anti-Minutemen stance, contributing to the fall of the organization.
Diamond City is divided between people living on the former baseball field and those 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 rich people who control the lion's share of the City's wealth. McDonough exploited this divide and favored the city's elite, which may have wanted 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. The irony of nuclear power first destroying the world then giving Diamond City its main advantage is not lost on the more scientifically-inclined members of the community.
The first establishments as one goes down the ramp into the city is the Publick Occurrences building that houses the local newspaper, and the All Faiths Chapel, the local church. Beyond that is the small circle of shops, that make up the Diamond City Market. West of the market place is the Diamond City security office and schoolhouse; behind the marketplace to the north is an alley containing the greenhouse, Moe Cronin's house, Arturo's house, Valentine Detective Agency, and Myrna's house; and to the south is the Dugout Inn, the local common house.
Further behind the market place in the southeast is the Science! Center, the Diamond City Radio building and Sheng Kawolski's house (built on top of a water collection pond). West of that is a garden and orchard, as well as a stage for addresses from Mayor McDonough.
The Stands are the southern district of the city where the more rich and affluent residents reside, like the Hawthorne, Cooke, Latimer, and Codman residences. It also houses the Colonial Taphouse, Diamond City's upscale tavern. Mayor McDonough's office is also in the Stands, requiring an elevator to get to the skybox.

- McDonough: "Everybody? Everybody! I need everyone's attention! I would like to address the subject that is on everyone's mind, and that is the disgusting article Piper has written... Diamond City has stood united for over 150 years. And what keeps us united are two things. First, is the great green guardian behind me. The Wall. Our protector and our savior from the filth of the outside. And second, is our faith and trust in each other. The faith and trust that has given us prosperity, security, and education for every citizen. And while the paper might point their fingers at synths and other ghost stories to drive us apart, we will not betray this sacred trust. Now I want everyone to hear these next words very carefully. I. Am not. A synth. I am the same flesh and blood boy who grew on these streets. Who was born in a shack just down the waterfront to Martha and Patrick McDonough. And I will not abandon my city due to the heinous allegations of the press. God bless this city. God bless the Wall!"

- Fallout 4 loading screen hints: "The Minutemen first rose to prominence in the year 2180, when they defended Diamond City against a horde of Super Mutant attackers."
- Fallout 4 loading screen hints: "In the year 2229, a mysterious visitor to Diamond City killed several people. It was only after he was shot dead by city security that the stranger was revealed to be a synth. The people of the Commonwealth have feared the Institute ever since."
- The Boogeyman Banished?: "Ever since the "Broken Mask" incident of 2229, right here in Diamond City, when the first human-looking synth infiltrated and attacked a group of innocent settlers, we have lain awake in bed at night, terrified of the Institute and everything it represents."
- The Sole Survivor: "Massacre of the CPG? What's that?"
Nick Valentine: "The Commonwealth Provisional Government. Years back a group of settlements tried to get together and form a coalition. Every settlement with even a hint of clout sent representatives to try and hash out an agreement. Only the Institute sent a representative of their own, a Synth. The man killed every rep at the talks. The Commonwealth Provisional Government was over before it even got off the ground. I took up in town not long after. I was damn lucky they didn't just tell me to scram right then and there."
(Nick Valentine's dialogue)
- Nick Valentine: "Hey. Let me ask you something. It's just, with everything that's happened with you, your family. It's a whole hell of a lot to process. I wanted to make sure you're holding up alright."
The Sole Survivor: "I don't know, Nick. My family's in tatters. I've been dropped into this place where everything's trying to kill me. You tell me."
Nick Valentine: "I'd expect you feel lost, scared, and mad as hell. I sure did. Took me a long damn time to get a feel for this place. Thank goodness I found Diamond City. It's got its flaws, sure, but it beats the hell out of anywhere else in the Commonwealth. Course, when I took up there back when, people were just as scared of the Institute as they are now, maybe more. The massacre of the CPG was still pretty fresh in people's minds at that point, and folks were still losing sleep over the Broken Mask. Plenty of people assumed I was just a saboteur, moving in to melt down the reactor or poison the drinking water. But, at the time, they couldn't exactly turn me away."
(Nick Valentine's dialogue)
- Fallout 4 loading screen hints: "Goodneighbor was founded in the year 2240, by a group of criminals who were banished from Diamond City."
- 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."
- Preston Garvey: "Mayor McDonough has always been against the Minutemen. I never quite understood why."
(Preston Garvey's dialogue) Note: This line is spoken at the entrance of Diamond City.
- The Sole Survivor: "Why did McDonough campaign against the Ghouls?"
Hancock: "Because he thought he could win. There'd always been a pretty clear divide between the folks living in the stands and those down on the field. I'm not convinced they didn't do it just to improve their view. 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.

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.
 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.
 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.
 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.
 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.
“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.
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.
 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).
 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).
 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.
 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.
 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.
 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.
 Codman Residence
Break in through the door (Advanced) to the home of the oldest family in Diamond City. The Codmans own the orchard."
