A Norwegian mercenary founded Gotham City and the British later took it over. During the American Revolutionary War, Gotham City was the site of a major battle. Rumors held it to be the site of various occult rites.
Shadowpact #5 by Bill Willingham expanded upon Gotham's occult heritage by depicting a being who has slept for 40,000 years beneath the land upon which Gotham City was built. Strega, the being's servant, says that the "dark and often cursed character" of the city was influenced by the being who now uses the name "Doctor Gotham."
In Gotham Underground #2 by Frank Tieri, Tobias Whale claims that 19th century Gotham was run by five rival gangs, until the first "masks" appeared, eventually forming a gang of their own. It is not clear if these were vigilantes or costumed criminals.
Many storylines have added more events to Gotham's history, at the same time greatly affecting the city and its people. Perhaps the greatest in impact was a long set of serial storylines, which started with Ra's al Ghul releasing a debilitating virus called the "Clench" during the Contagion storyline. As that arc wrapped, the city was beginning to recover, only to suffer an earthquake measuring 7.6 on the Richter Scale in Cataclysm. This resulted in the federal government cutting Gotham off from the rest of the United States in No Man's Land. This trio of storylines allowed writers the freedom to redefine the nature and mood of the city. The result suggested a harder city with a more resilient, resourceful, and cynical populace; a more dramatic and varied architecture; and more writing possibilities by attributing new locales to the rebuilding of the city.
In terms of atmosphere, Batman writer and editor Dennis O'Neil has said that, figuratively, "Batman's Gotham City is Manhattan below Fourteenth Street at eleven minutes past midnight on the coldest night in November."
Gotham City's atmosphere took on a lighter tone in the comics of the 1950s and part of the 1960s, similar to the tone of Batman stories of that era. However, by the early 1970s the tone of the city, along with that of the stories, had become grittier. Today, the portrayal of Gotham is a dark and foreboding metropolis rife with crime, grime, corruption, and a deep-seated sense of urban decay in the parts of the city not rejuvenated post-No Man's Land.
Different artists have depicted Gotham in different ways. They often base their interpretations on various real architectural periods and styles with exaggerated characteristics, such as massively multitiered flying buttresses on Gothic cathedrals or the huge Art Deco and Art Nouveau statuary seen in Tim Burton's movie version. Cyberpunk, Japanese, and Greek elements were presented in Joel Schumacher's series of films. The Christopher Nolan depiction of Gotham has featured distinct Chicago architecture and is cartographically based on the canon DC map of Gotham. Batman Begins features a CGI augmented version of Chicago while The Dark Knight more directly features Chicago infrastructure and architecture.
Within the Batman mythos, the person cited as being influential in promoting the unique architecture of Gotham City during the pre-American Civil War era was Judge Solomon Wayne, Bruce Wayne's ancestor. His campaign to reform Gotham came to a head when he met a young architect named Cyrus Pinkney. Wayne commissioned Pinkney to design and to build the first "Gotham Style" structures in what became the center of the city's financial district. The "Gotham Style" idea of the writers matches parts of the Gothic Revival in style and timing. In a 1992 storyline, a man obsessed with Pinkney's architecture blew up several Gotham buildings in order to reveal the Pinkney structures they had hidden; the editorial purpose behind this was to transform the city depicted in the comics to resemble the designs created by Anton Furst for the 1989 Batman film.
Arkham Asylum: Living Hell mentions the "Sprang Act", which forbids Gothamite businesses from advertising on rooftops. It was passed after minor villain Humpty Dumpty over-wound the mainspring of the city hall clock, causing the hour hand to jump off and strike one, causing a chain reaction.
After No Man's Land, Lex Luthor took the challenge of rebuilding Gotham City after the events of Cataclysm. Gotham's old Art-deco and Gothic structures were replaced with modern glass skyscrapers and buildings.
 Police and corruption
Common in Gotham is the rampant and recurring corruption within the city's civil authorities and infrastructure, most notably within the Gotham City Police Department. Commissioner Gillian B. Loeb had his hands in many pockets. However, Batman found evidence for conspiracy charges, forcing Loeb to resign his position. Subsequent commissioners were also corruptible, or open to various forms of influence. Batman has had to take on crooked cops, either acting in collusion with supervillains, working for the mob, or on their own. Later stories, featuring James Gordon as the new Commissioner, show the two characters often uniting to purge corruption from the force. Gordon was the commissioner for about 9 to 10 years of continuity, then retired, handing the police force over to his replacement, Commissioner Akins. Recent stories have returned Gordon to the position of Commissioner, unfortunately to find corruption taking a greater hold since his departure.

Gotham City's geography, like other fictional cities' geographies in the DC Universe, has varied over the decades, because of changing writers, editors, and storylines. The majority of appearances place Gotham on the Northeastern coast of the United States, where New York City is located. Also, Manhattan is an island in the Northeastern United States, which corresponds to maps depicting Gotham City. However, the Atlas of the DC Universe states that Gotham is located in New Jersey, across the Delaware Bay from Metropolis, which would place it on the southern coast of New Jersey.
Historically, "Gotham" has been a nickname for New York City originating on November 11, 1807 by Washington Irving in his Salmagundi Papers. For most of Batman's publication history in comics, Gotham has been assumed to be a New York City analogue. Frank Miller has said that "Metropolis is New York in the daytime; Gotham City is New York at night." DC Comics publisher and former president Paul Levitz says that Gotham is "New York from 14th Street down, the older buildings, more brick-and-mortar as opposed to steel-and-glass." The late New York Times journalist William Safire described Gotham City as "New York below 14th Street, from SoHo to Greenwich Village, the Bowery, Little Italy, Chinatown, and the sinister areas around the base of the Manhattan and Brooklyn Bridges.
Film adaptations have varied: Tim Burton's Gotham was based primarily on New York, while the films directed by Christopher Nolan have shown a Gotham more closely based on Chicago. In Nolan's films Batman Begins and The Dark Knight, the license plates of the cars registered in Gotham strongly resemble those of Illinois but display "Gotham" as the state. Additionally, during a car chase in Batman Begins one of the cops reports that Batman is travelling west on I-78. Nolan has stated that Chicago is the basis of his portrayal of Gotham, and the majority of both Batman Begins and The Dark Knight were filmed there. However, New York City's influence can be seen in "The Dark Knight," when the Joker refers to Gotham's "B and T" crowd, which is a New York nickname for commuters utilizing New York City's bridge and tunnel system. The Dark Knight Rises is being filmed in several US cities with the intention of depicting more of the various islands and districts of Gotham.
Many comic book series and characters are set in Gotham. Some of the most prominent characters directly connected to Batman whose adventures are set in Gotham are Nightwing, Huntress, Barbara Gordon and most recently Batwoman.
Other DC characters have also been depicted to be living in Gotham, including Jason Blood, Ragman, The Question, Plastic Man, Zatara and Zatanna, Simon Dark, and Tommy Monaghan, the anti-hero Hitman. The superhero teams Section 8 and the Justice Society of America have also been shown operating in Gotham City.
Within the DC Universe continuity, Batman is not the first hero in Gotham. Stories featuring Alan Scott, the Golden Age Green Lantern, set before and during World War II depict Scott living in Gotham, and later depictions show him running his Gotham Broadcasting Corporation. Additionally, the Justice Society of America, Doctor Fate, and the Golden Age Black Canary have been depicted as operating in Gotham. Black Canary's daughter, the Modern Age Black Canary, is based in Gotham through much of the Birds of Prey series. Arella (formerly Angela Roth), a supporting character in Teen Titans and mother of Titan member Raven, is shown in flashback to have resided in Gotham City as a teenager. A young Michael Carter would call the city home in the 25th century.
Apart from Gotham's superhero residents, the residents of the city feature in a back-up series in Detective Comics called Tales of Gotham City and in two limited series called Gotham Nights. Additionally, the Gotham City Police Department is the focus of the series Gotham Central, as well as the mini-series Gordon's Law, Bullock's Law, and GCPD.
Notable areas, landmarks, institutions and businesses
Gotham City is a major economic center within the United States of the DC Universe. Its important industries include manufacturing; shipping; finance; fine arts, represented by its numerous museums, galleries, and jewelers; and the production of giant novelty props. In addition to its commercial seaport, it also supports a naval shipyard.
Major businesses based in Gotham City include its most noteworthy corporation: Wayne Enterprises, which specializes in various industrial aspects and advanced technological research and development. Its charitable division, The Wayne Foundation, is a major supporter to the city's major charity, arts and research endeavors.
Noteworthy newspapers in Gotham City include the Gotham Gazette and the Gotham Globe. In the Silver Age comics, the editor-in-chief of Metropolis newspaper The Daily Planet, Perry White, had once worked for the Gazette early in his career.
Arkham Asylum is the primary but involuntary residence of many of Batman's foes. Dennis O'Neil named Arkham Asylum as an homage to the works of H. P. Lovecraft. For years, artists have rendered it predominantly as an old and sometimes crumbling structure, but at times some artists have depicted it as a more modern facility (notably, the storyline The Last Arkham involved Jeremiah Arkham tearing down the old asylum and replacing it with a modern structure more akin to a supermax prison). Its exterior and interior appearances often change to match the moods and needs of the creative team. In some stories, the rooms have the stereotypical white padded walls of a mental hospital, in others the brick or stone cells of an old-fashioned asylum, and in still others the glass and steel private rooms of a modern hospital. The suggestion often made is that its history in the city reaches back to the early part of the 20th century, and that its manager is always a member of the Arkham family. Its current manager is Jeremiah Arkham, the nephew of founder Amadeus Arkham. Perhaps the most notable trait of Arkham is that many writers have placed a seeming revolving door on it, whereby Batman's villains either escape or are freed very shortly after being admitted, allowing writers to use them without complications. Characters often comment on this situation, either comically or seriously remarking on the need for better security and care at Arkham.
Official Name: Arkham Asylum for the Criminally Insane
Aliases: Arkham; Arkham Hospital; Arkham Sanitarium; Mercey Mansion
Arkham Asylum is not just any institution for the criminally insane. It's the Ivy League of insanity. A "Harvard" for Psychopaths. Anything not described on the new inventory is contraband. Do not bring these items inside, no matter how small or commonplace they may appear. Bits and pieces do not fall through the cracks here. They fall into the hands of the best, the brightest and the sickest.
Arkham Asylum is located on the outskirts of Gotham City, and is where those of Batman's foes considered to be legally insane are incarcerated (other foes are incarcerated at Blackgate Penitentiary). Although it has had numerous administrators, its current head is Jeremiah Arkham. The Asylum does not have a good record, at least with regard to the high profile cases; escapes are frequent (on at least one occasion, an obsessive-compulsive multiple murderer was signed out of Arkham into the care of an incontinent, alcoholic vagrant, on the grounds that he "looked like a responsible citizen"), and those who are 'cured' and released tend to re-offend. Furthermore, several staff members, including at least one director, have ended up as residents, notably Dr. Jeremiah Arkham, Dr. Harleen Quinzel, Lyle Bolton and even the founder Dr. Amadeus Arkham and, in some incarnations, Doctors, Jonathan Crane and Hugo Strange.
Originally known as Mercey Mansion, the hospital was run by Amadeus Arkham. Arkham himself was slowly driven insane shortly following the grisly murder of his wife and child by a lunatic named Martin "Mad Dog" Hawkins. Dying inside his own hospital, custodianship of Arkham Asylum was passed down to his nephew, Jeremiah.
Jermiah Arkham took a hardline approach towards the care of his patients. He completely renovated the interior of the hospital, tearing away the old Victorian-style architecture, replacing it with newly designed interconnecting corridors patterned in the style of old classical labyrinths. With little regard for the hospital's dark history, Jeremiah was certain to destroy old remnants of the old asylum, including his uncle's private journal.  Arkham hired Hiram Contractors to handle the renovations. What Jeremiah didn't realize however was that the company foreman, Zolly Hiram, had been blackmailed by patient Victor Zsasz into building a secret corridor that connected to several padded rooms, including his own. This later enabled Zsasz to affect a temporary escape from the asylum.
Years ago, the original Arkham Asylum suffered massive structural damage when the criminal Bane orchestrated a large-scale break-out, setting dozens of patients free. As a result, Jeremiah Arkham was forced to close its doors and relocate. He established a new Arkham Asylum at the site of the abandoned estate of Eric Mercey on Mercey Island.
Jeremiah Arkham installed the most state-of-the-art security measures when he took control of the asylum. Video recorders were installed in every room and corridor with two guards stationed on every level twenty-four hours a day to discourage bribery. Even Arkham himself was required to present identification to access various levels of the hospital. All exterior windows at Arkham were installed with heat detectors and microwave motion detectors. Magnetic foils in the walls were used to block radio waves from penetrating locked cells. Although security protocols were highly efficient, they were not foolproof. Within weeks of the renovations both Mister Zsasz and Batman succeeded in breaking out of the asylum. Additionally, Batman's former partner, Nightwing even succeeded in breaking into Arkham.
The Batcave is the secret headquarters of Batman consisting of a series of subterranean caves beneath Wayne Manor.
Originally, there was only a secret tunnel that ran underground between Wayne Manor and a dusty old barn where the Batmobile and Batmicrolite were kept. Later, in Batman #12 (August–September 1942), Bill Finger mentioned "secret underground hangars." In 1943, the writers of the first Batman movie serial gave the Caped Crusader a complete underground crime lab and introduced it in the second chapter entitled "The Bat's Cave". The entrance was via a secret passage through a grandfather clock and included bats flying around.
Bob Kane, who was on the movie set, mentioned this to Bill Finger who was going to be the initial scripter on the Batman daily newspaper strip. Finger included with his script a clipping from Popular Mechanics that featured a detailed cross section of underground hangars. Kane used this clipping as a guide, adding a study, crime lab, workshop, hangar and garage. This illustration appeared in the Batman "dailies" on October 29, 1943 in a strip entitled "The Bat Cave!"
In this early version the cave itself was described as Batman's underground study and, like the other rooms, was just a small alcove with a desk and filing cabinets. Like in the movie serial, the Batman's symbol was carved into the rock behind the desk and had a candle in the middle of it. The entrance was via a bookcase which led to a secret elevator.
The Batcave made its comic book debut in Detective Comics #83 in January 1944. Over the decades, the cave has expanded along with its owner's popularity to include a vast trophy room, supercomputer and forensics lab. There has been little consistency as to the floor plan of the Batcave or its contents. The design has varied from artist to artist and it is not unusual for the same artist to draw the cave layout differently in various issues.
The cave was discovered and used long before by Wayne's ancestors as a storehouse as well as a means of transporting escaped slaves during the Civil War era. The 18th century frontier hero Tomahawk once discovered a gargantuan bat (owned by Morgaine le Fey of Arthurian legend) inside what can be assumed will become the Batcave. Wayne himself rediscovered the caves as a boy when he fell through a dilapidated well on his estate, but he did not consider the cave as a potential base of operations until he rediscovered it yet again when he returned to Gotham to become Batman. Much like Superman's Fortress of Solitude, the Batcave serves as a place of privacy and tranquility.
In earlier versions of the storyline, Bruce Wayne discovered the cave as an adult. In "The Origin of the Batcave" in Detective Comics #205 (March 1954), Batman tells Robin he had no idea the cave existed when he purchased the house they live in. He discovered the cave by accident when testing the floor of an old barn on the rear of the property, and the floor gave way. This story also established that a frontiersman named Jeremy Coe used the cave as a headquarters 300 years earlier. Bruce Wayne discovering the cave as an adult remained the case at least through Who's Who #2 in 1985.
Upon his initial foray into crime-fighting, Wayne used the caves as a sanctum and to store his then-minimal equipment. As time went on, Wayne found the place ideal to create a stronghold for his war against crime, and has incorporated a plethora of equipment as well as expanding the cave for specific uses.
Often, Bruce Wayne is depicted as having discovered the cave as a child, falling into it during exploration of the grounds in his youth. This was shown in the movies Batman Forever and Batman Begins, as a young Bruce Wayne fell through the wooden cover of an abandoned water well.
The cave is accessible in several ways. It can be reached through a secret door in Wayne Manor itself, which is almost always depicted as in the main study, often behind a grandfather clock which unlocks the secret door when the hands are set to the time that Bruce Wayne's parents were murdered, 10:47 P.M. In the 1960s Batman TV show, the study entrance has been shown to be behind a bookcase which was revealed when Bruce Wayne (actor Adam West) activated a red control switch hidden in a statue of William Shakespeare; which slides to the side when a secret switch is turned, revealing the "Bat-Poles", which allow Bruce Wayne and his ward to change into their Batman and Robin costumes en route as they slide down to the cave. An entrance under Bruce Wayne's chair in his office in Wayne Enterprises, as shown in Batman Forever, connects to a miles-long tunnel which Bruce travels through in a high-speed personal transportation capsule. In Batman Begins, the cave is accessible through a secret door disguised as part of a large display case and unlocked by pressing a sequence of keys on the nearby piano.
Another secret entrance, covered by a hologram, waterfall or a camouflaged door, allows access to a service road for the Batmobile. Another alternate entrance is the dry well where Bruce originally discovered the Batcave, highlighted especially during the Knightfall storyline. At one point, Tim Drake and Dick Grayson use the dry well to get into the cave, which they had been locked out of by Jean Paul Valley during his time as Batman, and Bruce Wayne used it to infiltrate the cave and confront the insane Valley in the final battle between the two men for the title of the Batman. Lured into the narrow tunnel, Valley was forced to remove the massive bat-armor he had developed, thus allowing Wayne, who was wearing his normal, slim outfit, to force him out of costume and renounce his claim to the title.
The location of the cave is known not only to Batman, but to several of his allies. In addition to the so-called "Batman Family", members of the Justice League and the original Outsiders are aware of the cave's location. Essentially, anyone who is aware of Batman's secret identity also knows the location of the Batcave, much like how people who have knowledge of Robin's identity have knowledge of Batman's; these, unfortunately, include such villains as Ra's al Ghul, who makes occasional visits to the Batcave to confront his long-time nemesis, and David Cain, who infiltrated the cave during the Bruce Wayne: Fugitive storyline when he framed Bruce Wayne for murder.
The Batcave serves as Batman's command center, where he monitors all crisis points in Gotham and the world.
The cave's centerpiece is a supercomputer whose specs are on par with any of those used by leading national security agencies; it permits global surveillance and also connects to a massive information network as well as storing vast amounts of information, both on Batman's foes and his allies. A series of satellite link-ups allows easy access to Batman's information network anywhere around the globe. The systems are protected against unauthorized access, and any attempt to breach their security immediately sends an alert to Batman or Oracle. Despite the power of Batman's computers, the Justice League Watchtower is known to have more powerful computers (composed of Kryptonian, Thanagarian and Martian technology), and Batman does occasionally use them if he feels his computers are not up to the task; on occasion he also consults Oracle for assistance.
The Batcomputer as presented in Batman & Robin is powerful beyond the realm of realistic computer systems, as Alfred Pennyworth is able to program a replication of himself (his "brain algorithms") that is capable of conversation.
Additionally, the cave features state-of-the-art facilities such as a crime lab, various specialized laboratories, mechanized workshops, personal gymnasium, a vast library, parking, docking and hangar space (as appropriate) for his various vehicles as well as separate exits for each type, trophies of past campaigns, a large bat colony, and a Justice League teleporter. It also has medical facilities as well as various areas used in training exercises for Batman and his allies.
The cave houses Batman's vast array of specialized vehicles, foremost being the famous Batmobile in all its incarnations (mostly for nostalgia, but also for contingencies, as all are serviceable and in excellent working condition). The 1990s animated series gave rise to the idea that Batman keeps a fleet of regular cars of various models and utility vehicles such as an ambulance when the Batmobile would be too conspicuous for a given mission. Other vehicles within the complex include various motorcycles, air- and watercraft such as The Bat-Wing, a single-occupant supersonic jet, and the Subway Rocket.
The cave is sometimes powered by a nuclear reactor, but most often by a hydroelectric generator made possible by an underground river.
Later comics, specifically the Cataclysm storyline, suggest that Batman has incorporated safeguards against earthquakes and even a potential nuclear catastrophe, outfitting the cave as a virtual bomb shelter or an enhanced panic room. The city's earthquake redesigned the caverns of the Batcave, with eight new levels now making up Batman's secret refuge of high-tech laboratory, library, training areas, storage areas, and vehicle accesses. It also includes an "island" computer platform (built on the spot where the Batmobiles' hydraulic turntable once was) with seven linked Cray T932 mainframes and a state-of-the-art hologram projector. There's also a selection of retractable glass maps within the computer platform. Kevlar shieldings are prepared to protect the cave's computer systems from its seismic activity. With the cave's various facilities spread amid limestone stalactites and stalagmites, Batman built retractable multi-walkway bridges, stairs, elevators, and poles to access its facilities.
There is a containment vault solely for Lex Luthor's Kryptonite ring. However, it is recently revealed that Batman built another containment facility within the cave for a collection of variety of forms of the Kryptonite.
What is allegedly the world's last Lazarus Pit was constructed inside the cave, although this has been contradicted by events in the pages of Batgirl and the Black Adam miniseries.
The Batcave is rigged with the most sophisticated security system in the world in order to prevent all measure of infiltration. The security measures include motion sensors, silent alarms, steel and lead mechanical doors which could lock a person in or out, and a security mode which is specifically designed to stop if not eliminate all Justice League members in the event that any of them go rogue.
The cave stores unique memorabilia items collected from the various cases Batman has worked. Originally, these were stored in a room designed just for them; it was explained that Batman and Robin took one memento from each case. Later, the trophies were shown to be in the large main area of the cave, residing among the rest of the Batcave's furnishings.
The most famous and prevalently featured are a full-size animatronic Tyrannosaurus Rex, a giant Lincoln penny, and an oversized Joker playing card. The T. Rex comes from an adventure on "Dinosaur Island"; the penny was originally a trophy from Batman's encounter with a penny-obsessed villain named the Penny Plunderer.
Other pieces often shown in the Batcave are Two-Face's original coin, Deathstroke's sword (the owner of which Batman has fought at least twice), the shroud of the vampiric Monk, and over-sized ten-pins.
There is also a glass case display of Jason Todd's Robin costume as a memorial to him, with the epitaph "A Good Soldier", which remains even after Todd's resurrection. Barbara Gordon's Batgirl costume also remains on display.
