Before the bombs fell, this location used to be called Scollay Square, a name that can still be seen in the Third Rail on the wall to the right side of the bar. Goodneighbor was founded in 2240 by criminals who were exiled from Diamond City. It can be easily reached from the Mass Fusion building by traveling to the southeast.
The town is known for its criminal activity, such as murder, extortion and chem peddling. There are two shops near the entrance: Kill or Be Killed is run by KL-E-0 who sells weapons, and Daisy's Discounts run by Daisy who sells general items. The Third Rail is the town bar built out of an old subway station tended by Whitechapel Charlie. It is owned by the self-appointed and beloved mayor, John Hancock.
The residents of Goodneighbor dress and act like stereotypical mobsters. People in Diamond City say "they come from the pressed suit and tommygun school of thuggery" and "in Goodneighbor two things count, style and body count." A good example of this are the Triggermen, mafia-like groups operating out of secret bases such as Vault 114 in Park Street station. Goodneighbor residents are vehemently opposed to the Institute and show contempt towards the denizens of Diamond City, especially Mayor McDonough.
Goodneighbor can also be accessed by the Fallen Skybridge at the collapsed section by simply jumping down into the city, which forces a loading screen. This can also be done by using the the jet pack mod for power armor to jump over the main gate.
There are also three locked doors marked "Warehouse" in Goodneighbor. Whitechapel Charlie in the Third Rail offers a quest (after browsing his wares) to clear these buildings of hostiles. All three doors are Novice locks, and all three areas are filled with Triggermen. As long as one sneaks into these houses, nobody in Goodneighbor will attack upon leaving.
Three Triggermen and the corpse of a drifter can be found in an alley behind Hotel Rexford. The former will start fighting on being approached.
Goodneighbor can be exited through the back of the aforementioned alley by climbing to the highest vertical point of the power box and jumping across the trash bins and over the steel wall.
If the Sole Survivor brings Deacon to Goodneighbor, he will change his outfit to appear similar to the mobsters around the town.
Hancock mentions that Goodneighbor used to be run by a man called Vic, and his gang. They used to use the drifters, including Hancock, for their own work. He then goes on to say that him and some of the other drifters attacked Vic and his gang overnight and that he then became mayor of Goodneighbor.
If one enters Goodneighbor before joining The Railroad, Deacon can be found wandering around near Kill or Be Killed.
The following is based on unverified behind the scenes information and has not been confirmed by canon sources.
In the real world, Mary Goodneighbor was a burlesque performer who was filmed in the Old Howard Theater by Boston's vice squad performing a striptease. This tape was central to getting the Old Howard Theater shut down, marking the general end of the Scollay Square district.
In the game, the Memory Den is in the structure that used to be the Old Howard Theater. The proprietor of the Memory Den, Irma, is also named and styled after Mary Goodneighbor, whose stage name was Irma the Body.
The Good Neighbor Program is a real world Section 8 housing program in the Commonwealth of Massachusetts, so it's possible that it could be the basis for Goodneighbor's name.

This prevents the player from opening the nearby safe as it can only be unlocked via Bobbi's terminal. With the console command 'unlock', one can access the safe, though there will be no prompt indicating that the safe exists.[verified]
