"They fill the island full of crazy people. Then they act all surprised when something actually happens."
—A security guard on Joker's takeover

Secluded from the mainland, the historic Elizabeth Arkham Asylum for the Criminally Insane (known simply as Arkham Asylum) was originally owned by Amadeus Arkham and named after his late mother. While originally containing only the Arkham Mansion and the Botanical Gardens, the institution gradually developed and became a medical facility and criminal penitentiary that was dedicated to helping those who were deemed criminally insane and afflicted with extreme mental illnesses.

History

"Gotta say, it's good to be back!"
—Joker upon arrival.

Amadeus Arkham originally founded Arkham Asylum in the memory of his mother, who he euthanized as treatment for dementia. The historic facility was built on the grounds of the Arkham family's historic mansion on the outskirts of Gotham City on the secluded Arkham Island.

The entrance to Arkham.

Amadeus personally treated its first inmate Martin Hawkins, who had killed his wife and daughter. After being claimed sane enough to walk free, Martin was due to be released until he murdered Amadeus's secretary. At some point Martin also went to the Botanical Gardens on the island and desecrated the statue raised by Amadeus in memory of his family. These many tragedies pushed Amadeus over the edge, and during a session of electroshock therapy he murdered Martin. Amadeus was later ruled insane and incarcerated in his own asylum where he died. His gravestone was located next to the Botanical Gardens.

Over the years, the asylum gradually developed with new facilities such as the Penitentiary being established. However, it was eventually closed down soon before the Arkham Origins Incident - possibly because more criminals were instead sent to Blackgate Prison which later proved to be unfit for housing the criminally insane. Once reopened, the facility was voted as the number one psychiatric and rehabilitation facility in the state. However, the infamous reputation remained as more high-profile criminals frequently managed to escape its walls.

It developed to become a premium 500-bed psychiatric facility holding a range of individuals deemed insane. For the past two years prior to the Arkham Asylum Incident, the facility offered internships to University Students to help them gain valuable experience for a career. Arkham Asylum's own website called ArkhamCare was the online public face of the facility that was designed to inform potential patients about the institution.

Incident Reports

Pre-Arkham

During that time, Arkham Asylum had developed from the Arkham Mansion and Botanical Gardens into the Elizabeth Arkham Asylum for the Criminally Insane thanks to Amadeus Arkham. The institution gradually developed, but was eventually abandoned, possibly because more of Gotham's criminals were being sent to Blackgate Prison instead of Arkham Asylum.

Arkham Origins Incident

Arkham Asylum could be seen in the distance from Gotham's mainland, but during that incident was not operational, so the criminally insane individuals were mostly treated within other institutions such as Blackgate. However, Quincy Sharp spoke about his intentions to renovate and reopen the asylum in the following months so it would function as a highly appropriate facility to house and treat those with severe mental illnesses.

Cold, Cold Heart Incident

While Batman took down Mr. Freeze and Ferris Boyle, Arkham was being redeveloped by Sharp into the psychiatric institution that it was formerly.

Arkham Origins Blackgate Incident

At around the same time of this incident, Arkham Asylum had been fully renovated and was in a fit condition to house the criminally insane thanks to the efforts of Sharp who became the new Warden. Facilities such as the Intensive Treatment Center and Medical Facility were drastically developed so the asylum could also function as a hospital while the improved Penitentiary ensured that the growing number of super-criminals remained safely incarcerated.

Fully Renovated

Very soon, after the Arkham Origins Blackgate Incident, patients such as the the Joker were transferred to Arkham, so that they could receive the optimal level of treatment for psychological illnesses. Additionally, new staff were employed there.

Over the years, Arkham Asylum further improved to become a leading institution for psychiatric research with new facilities such as laboratories being added, and with new cells such as Extreme Isolation being added to house a wider variety of insane patients.

Assault on Arkham Incident

The Riddler was incarcerated by Batman in the facility, after he attempted to interrogate him about a dirty bomb the Joker stole. Because of this, the Suicide Squad (by that point composed of veterans Deadshot, Harley Quinn, and Captain Boomerang as well as newcomers Black Spider, King Shark, and Killer Frost) were dispatched by Amanda Waller to infiltrate the asylum to find classified data the Riddler had allegedly stolen from their mainframes. Although they ultimately managed to infiltrate the asylum with help from the Penguin, they ran into a few snags due to an unexpected encounter with the Joker, as well as a gas explosion causing a yellow alert, the latter of which forced them to swap security footage videos in a failed attempt at delaying Batman's interference. They ultimately went against their mission after they learned not only that the real mission was to assassinate the Riddler, but also the reason why due to his having knowledge on how to diffuse the nanite bombs (due to Riddler having formerly been a Suicide Squad member himself), which they promptly used to disable their own bombs, although at the cost of the lives of both Black Spider (due to Batman swapping places with him) and King Shark (due to his tough skin making the electro-shock method useless). Joker, who escaped due to exploiting a weakened part of the security defenses via Harley Quinn's earlier attempt at revenge towards him, also proceeded upon recovering the dirty bomb via Harley's mallet, engineer a jailbreak of the various inmates as insurance that Batman cannot stop his plan in time. Harley ultimately defected back to the Joker, while Killer Frost was thrown while inside of a police car into a mountain by Bane, Captain Boomerang was left at the Asylum, while Deadshot was the only one to actually escape besides Joker and Harley Quinn.

A Matter of Family Incident

Arkham Asylum could be seen relatively close to the Seagate Amusement Park that Robin and Batgirl were on while trying to save James Gordon from the Joker and Harley Quinn. The psychiatric institution remained operational during that time with a number of insane individuals as well as insane super criminals who were incarcerated there away from the Gotham City mainland.

Arkham Asylum Incident

Following a number of the patients' breakout attempts over the years, Warden Sharp had the asylum's security and facilities greatly improved to ensure inmates did not escape - something quickly noticed by the Joker. For example, new electrical barriers, Suicide Collars, weapon detectors and CCTV cameras were introduced to ensure that the patients' behavior could be more easily controlled.

Despite that, a mysterious fire at Blackgate resulted in all of the Blackgate Prisoners being transferred to Arkham Asylum, which put a great strain on the facilities. That proved to be problematic as the staff could not closely monitor so many prisoners, which resulted in Harley Quinn being able to escape and sneak to the Security Control Room. During that incident, the asylum was gradually desecrated by the patients, and Poison Ivy's Plants were mutated by Titan which damaged a large section of the asylum.

Arkham City Incident

Using the Arkham Asylum Incident in his favor, Sharp became Mayor of Gotham City and proposed the creation of Arkham City: a sectioned off quadrant of Gotham City that was devoted to the incarceration of Arkham patients and convicts alike. Once Arkham City had been approved, Mayor Sharp ordered that Arkham Island be sold. A number of prominent companies bid for the land, but it ultimately went to the previously unknown security company TYGER.

Within weeks of the sale, TYGER was also awarded the contract to police Arkham City and instantly began using Arkham Island to launch its fleet of helicopter gunships to police the new prison facility. After Arkham City shut down, so did the Asylum, which was abandoned altogether.

As seen from Arkham City, the damage of Poison Ivy's vines had not been removed by that time.

Arkham Unhinged Incident/Arkham Knight Comics Incident

Around the time of the Joker's death, Joker posthumously revealed that the walls of Arkham City were rigged to blow, and he hinted that the answer to defusing them would be at the Intensive Treatment Center cell that he was once incarcerated in after an incident on the Fourth of July. That section of Arkham Asylum ended up being destroyed by a bomb rigged inside the cell, which nearly resulted in Batman's death, though he escaped. The Arkham Knight also went over there, deduced that the cell was rigged, and did not want Batman be killed before he had his shot at him, although after he found the Joker's "Die-ary", he mentioned that the night wasn't a total loss.

Arkham Knight Incident

With Arkham Asylum abandoned by TYGER, Scarecrow took over the Arkham Mansion as his secret base, arranged a meeting with the other super-criminals, and devised a plan to 'break' Batman. Once again, the asylum could be seen from the Gotham City mainland, and was in the exact same condition as the Arkham Asylum Incident.

Scarecrow kidnapped Robin and Commissioner Gordon, took them to the asylum, and forced Batman to turn himself in to save them. Scarecrow took Batman to Arkham Asylum where he had him rolled in on a prisoner gurney, much like the way that Batman and the guards brought in the Joker in Arkham Asylum two years earlier. Scarecrow had Batman transported in a truck to the Arkham Mansion, which was still overrun with Ivy's plants. It was here that Scarecrow revealed Batman's secret identity as Bruce Wayne to the world. However, Jason Todd (who had a change of heart after an earlier fight with Batman), tracked Scarecrow's truck, arrived in time to stop him from killing a restrained Batman and rescued his mentor, who managed to inject Scarecrow with his own Fear Toxin, and effectively ended the Master of Fear's reign of terror over Gotham City.

After Arkham Knight Incident

Sometime after the Arkham Knight Incident, A.R.G.U.S. stepped in to rebuild the facility, enacting extensive and expensive renovations and upgrades, most of which came from government funding, but some also originating from donations by the Wayne Foundation. Under this new arrangement, A.R.G.U.S. now had sole federal jurisdiction over the facility. Having lobbied to refurbish the facility from the beginning, Director Amanda Waller reassured members of the United States Congress that this time no one who they didn't want to get out would be able to get out, with the same being said for those wanting to get in.

Kill the Justice League Incident

Five years following Scarecrow's attack on Gotham, Arkham Asylum has been reopened as the city's main facility to house the criminally insane, with even Aaron Cash returning to his previous role in Arkham.

Along with Harley Quinn having been in the asylum for five years, three other less insane patients were brought to Arkham by order of Amanda Waller; the self declared rival of the Flash, Captain Boomerang, a shark like demi-god going by the alias King Shark and a man claiming to be the recently killed Floyd Lawton. Within the walls of the asylum the four of them were informed by Waller that they would be joining Task Force X, informing them that she only needs one of the four to join the team, Waller left a nano-bomb injector on a table and left the four inmates, making them believe this was a test to see which of the four would remain bomb free. However, during the ensuring fight for the nano-bomb injector, all four were injected and now had bombs in their heads, Waller officially welcoming them to the team and sending them away from Arkham and to Metropolis for their first assignment.

Facilities

Visitor Center

  • Being the only location that visitors could access, this location was designed for relatives to be able to safely visit patients under close surveillance by the asylum's security. The Visitor's Center included a reception desk for visitors to sign in, as well as multiple booths behind glass in which the patients sat behind when they talked to their relatives.

Intensive Treatment Center

  • A large facility located in the center of Arkham Island, the Intensive Treatment Center held a number of the more extreme personalities and was designed to provide care for highly severe psychological and physical illnesses. This unit contained a number of holding cells, many offices for the Arkham Staff along the corridors, the Extreme Isolation cells, a wide range of medical equipment, the island's main lobby, and access to the sewer where Killer Croc was housed. This was one of the island's most highly secure buildings where patients are first admitted for initial assessments, so it had up-to-date security systems to properly house inmates.

Medical Facility

  • One of the newer additions to the Arkham Asylum, the Medical Facility was one of the primary locations for the criminally insane inmates of the institution to receive physical treatment, alongside the Intensive Treatment Unit. This building had a sanatorium with an X-Ray Room, a Patient Observation Room and a Surgery Room leading off from it as well as an elevator which lead to the lower floor where Dr. Harleen Quinzel's abandoned office could be found. The entire interior appeared modern yet decayed, possibly due to patients mistreating the facility.

Penitentiary

  • The primary location for incarceration, the Penitentiary contained a great number of different cells to house the asylum's extreme variety of inmates. In the center, cells for the Arkham Lunatics were located which lead into various wings. The Green Mile was the primary housing location of Poison Ivy which was located along the corridor to the Security Control Room - the main room for where the whole asylum's security measures were controlled. The unit also contained the Extreme Incarceration cells where a number of Gotham's super-criminals such as Mr. Freeze were housed.

The Arkham Mansion

  • The oldest building on the island, the Arkham Mansion was originally the home of the Arkham Family until Amadeus Arkham decided to turn the island into the Elizabeth Arkham Asylum for the Criminally Insane. This was constructed with a Gothic, Victorian architecture with a large clock tower located on top of the mansion. Inside, the Arkham Mansion contained long corridors that lead to various rooms such as the Library, Dr. Young's Office, the Arkham Records Room, the Warden's Office, and Amadeus Arkham's Cell.

The Botanical Gardens

  • One of the oldest structures on the island, the Botanical Gardens were located next to the Arkham Mansion. These gardens functioned as a place of leisure for inmates to visit in their free time, evident by Humpty Dumpty's deconstructed toys located on a bench in there. These gardens also offered a location for doctors to study biological research, such as in the Titan Production Facility. The Botanical Gardens were filled with an assortment of plants as well as rooms such as the Elizabeth Arkham Glasshouse that was dedicated to Amadeus' mother.

Arkham Asylum's Underside

  • Located deep beneath the surface of Arkham Asylum, the sewer systems were accessible through the Intensive Treatment Center elevator where Killer Croc was incarcerated or through an abandoned door leading from Arkham North. This contained tunnels of sewers, old brick corridors, a Pump Control Room, as well as a hidden Batcave that was designed for any breakout attempts. The system was poorly maintained. However, it was occasionally visited by the Arkham Staff to assess, incarcerate, or treat Killer Croc.

Extreme Isolation

  • Extreme Isolation is an area of Arkham that is located in the Intensive Treatment Center and reserved for only the most dangerous of inmates. An almost inescapable prison, the only way in and out of the area is via a high-security, metal transfer box. The entrance is also guarded by six heavily armed and armored security guards at all times. Notably this was the only area that Batman was not able to infiltrate and was apparently not a concern of the Dark Knight as he never mentioned it again after its inital debut suggesting that it is the most secure area on the island. The only known inmate from the Extreme Isolation seen was the Titan Henchman whom had previously been banished there by Dr. Penelope Young and then released by the Joker. Rumors persist that this may have been where the Joker and the Scarecrow were kept when imprisoned.

Trivia

  • Before the events of Arkham Asylum, Jason Todd was kidnapped and tortured by Joker for over a year in an abandoned part of Arkham while it was still open. The precise whereabouts of this remain unknown, although it possibly took place in Amadeus's former cell in the Arkham Mansion which would explain the presence of his carved symbols and writings that could be seen on the floor. In Batman: Arkham VR the background looked like the Medical Facility. However, there was also a row of cells with electric bars outside the Intensive Treatment Center only seen on various security monitors.
  • The chimneys on the Intensive Treatment Center, though present during Arkham Asylum could not be seen during Batman: Arkham City or Batman: Arkham Origins. The reason for this is unknown though it may have been a continuity error.
  • Throughout the Arkham series the Asylum has been through a state of closures and reopenings; It had been closed for a number of years before plans to reopen it were mentioned in Arkham Origins, it was closed down after the opening of Arkham City and used as a base for the TYGER guards after Joker's takeover of the Asylum, and was left abandoned following the closure of Arkham City and used as a hideout by Scarecrow as shown in Arkham Knight. Currently, as of Suicide Squad: Kill the Justice League, Arkham Asylum has been reopened and operational again for five years following Scarecrow's attack on Gotham.
