The Xavier Institute for Higher Learning
|Notable locations||Salem Center, New York|
Xavier Institute's Students & Faculties
|First appearance||The X-Men #1|
The X-Mansion is the common name for Professor Xavier's mansion. It is the base of operations and training site of the X-Men and the location of a school for mutant teenagers, and sometimes older aged mutants, the Xavier Institute for Higher Learning, formerly Xavier's School for Gifted Youngsters. It is also the worldwide headquarters of the X-Corporation. Its address is 1407 Graymalkin Lane, Salem Center (part of the town of North Salem), located in the very northeast corner of Westchester County, New York. The school's motto is "mutatis mutandis." Recently, Wolverine re-opened the school, at the same address, under the name of the Jean Grey School for Higher Learning.
The X-Mansion is the inherited property of Charles Xavier (Professor X) and has been in the Xavier family for ten generations including two known mutants in the lineage, both becoming detached from the family. Little else is known about them or their mutations.
As Xavier's School for Gifted Youngsters, the X-Mansion was the training site of the first two generations of teenage X-Men:
- The original X-Men — Cyclops, Iceman, Angel, Beast, Jean Grey (Marvel Girl), and later, Mimic (briefly), Havok, and Lorna Dane
- The original New Mutants — Cannonball, Wolfsbane, Mirage, Karma, Sunspot, Cypher, Magma, Magik, and Warlock, along with Shadowcat, a contemporary of the original New Mutants who was their classmate but was a member of the adult X-Men team instead.
In X-Men vol. 2 #38 (November 1994), the X-Mansion was renamed from Xavier's School for Gifted Youngsters to the Xavier Institute for Higher Learning, as most of the X-Men were adults rather than teenagers by this time. Xavier's School for Gifted Youngsters was relocated to the Massachusetts Academy in Western Massachusetts (a Marvel created town or region called Snow Valley somewhere in The Berkshires), which served as the training site of the third generation of teenage X-Men, Generation X, beginning in Generation X #1 (November 1994).
The Massachusetts Academy closes permanently in Generation X #75 (June 2001). Shortly thereafter, the school for young mutants is reopened at the X-Mansion, but the name remains "The Xavier Institute for Higher Learning" despite the younger student body. The fourth generation of mutant teenagers, featured in Grant Morrison's New X-Men (2001–2004) and in New Mutants (2003–2004; relaunched as New X-Men: Academy X, July 2004–February 2008), study at the mansion until it is destroyed during the 2007–2008 story "Messiah Complex" and the X-Men subsequently disband and close the Institute.
Though protected by high-tech defenses, the X-Mansion has often been breached by the supervillains and evil mutants faced by the X-Men. Indeed, the X-Mansion has been destroyed and rebuilt several times. It was demolished in a battle with the Sidri in Uncanny X-Men #154 (February 1982) and atomized by Mister Sinister in Uncanny X-Men #243 (April 1989). It was rebuilt by a future Franklin Richards in moments but reverted to its destroyed state after the time-traveler became confused.
Certain portions of the mansion, such as extensive sub-basements, survived both demolitions. When Onslaught revealed himself and fought the X-Men (X-Men v2 #54 (June 1996) and Onslaught: X-Men), the mansion took heavy damage, though was quickly repaired in-between issues after the "Onslaught" storyline. In Operation: Zero Tolerance, Bastion forced Jubilee to reveal the mansion's defenses. He then stripped down the mansion, having everything inside the mansion removed, even down to the paint on the walls. After defeating Bastion, the X-Men moved back into the mansion, as detailed in X-Men v2 #70 (November 1997). The X-Mansion survived an assault by the Shi'ar Imperial Guard in New X-Men #122-126 (March–July 2002) as well as a riot by students led by Quentin Quire in New X-Men #134-138 (January–May 2003). In the Planet X storyline of New X-Men #146-150, however, the X-Mansion was destroyed; the rebuilding process could be seen in New X-Men #155-156 (June 2004). In the wake of M-Day the mansion was infiltrated by followers of the Reverend William Stryker in an attempt to wipe out the students, resulting in some structural damage and several casualties. Then the mansion was severely damaged when the Danger Room became sentient and summoned local machinery to attack the structure. The mansion was also damaged when Mr. Sinister's new team of Marauders attacked the mansion. A fight between the Hulk and several mutants heavily damaged the mansion. In the Messiah Complex storyline, the mansion was completely destroyed by attacking Sentinels.
Unlike past times, the mansion was not rebuilt for a considerable length of time. Rather, the X-Men and their students relocated to a new base of operations in San Francisco. Under the name Graymalkin Industries, the new X-base is not run as a school, but rather as a sort of community center for mutants who wish to develop their powers.
Faculty (pre-"Messiah Complex")
- Shadowcat teaches computer science classes and, in addition to being a member of the senior staff, acts as a student advisor and liaison for the senior staff.
- Karma teaches French and is in charge of those students who are too young to join the training squads. She also oversees the library.
- Nightcrawler teaches music, art, life sciences, and drama.
- Beast teaches science and mathematics and is part of the senior staff, presumably overseeing the curriculum.
- Emma Frost, besides being the headmistress of the Xavier Institute, also teaches English, business, and ethics, much to the horror of Kitty Pryde. She also presides over the new team of X-Men, teaching them to work as a team, with some assistance from the senior staff, such as Colossus.
- Wolverine teaches close quarters combat.
- Cyclops, besides being the headmaster of the Xavier Institute, also teaches the elective leadership and tactics.
- Northstar, before his death (and later resurrection), taught business and consumer law classes, as well as a flying class for those students with flight powers. He also mentored the Alpha Squadron training squad.
- Iceman, being a Certified Public Accountant, teaches classes in mathematics, finance, and accounting.
- Gambit teaches a target practice class for students with projectile-based powers. He also mentors the Chevaliers training squad.
- Wolfsbane, in addition to mentoring the Paragons, is a teaching assistant in Beast's science class.
Post X-Men: Schism
After the events of X-Men: Schism, Wolverine and half of the X-Men return to Westchester, New York and the X-Mansion. The name of the school is now the "Jean Grey School for Higher Learning." Its grounds are in fact a spawn of Krakoa the Living Island. In the first issue of Wolverine and the X-Men an entirely new school is built on the grounds. It is funded mainly with scientific advancements by the students.

In the middle of the main courtyard is the Phoenix Memorial Statue, dedicated to the memory of Jean Grey. Notable rooms include the Danger Room and a room containing Cerebro. The Headmasters Office of Cyclops and Emma Frost is on the top floor. The basketball court is a popular hang-out; it was the site of a well-known basketball game in X-Men v2 #4 (January 1992) in which the X-Men used their mutant powers. Directly below the basketball court is the hangar, which houses many transportation vehicles, as well as aircraft such as the X-Men Blackbird.
Age of Apocalypse
The remains of the X-Mansion were the headquarters for a mutant resistance cell against Apocalypse - a mutant that had conquered North America. The Mansion survives, and many new mutants come to the School in hope of shelter.
Prelude to Deadpool Corps
In issue #2, the X-Mansion is shown to be an orphanage for troubled kids that is run by Prof. X and the teachers include Storm and Beast. Some of the orphans include kid versions of Deadpool, Scott Summers, Wolverine, Angel and Colossus.
In the Ultimate universe, the X-Mansion does not differ much; however, it is not entirely funded by inheritance. Though the school originally was funded from Magneto's inheritance, allowing them to neither accept nor seek out donations. Its policies have since changed after Magneto's departure and Xavier's subsequent control over the facility. Later, the students question and ridicule the unlikeliness of the facility simply being funded by inheritance.[volume & issue needed] It is then revealed that numerous donors fund Xavier's projects and remain anonymous due to heavy anti-mutant sentiments present in public opinion.[volume & issue needed] One of the biggest donors was the Hellfire Club, who were revealed to have an ulterior motive for doing so.[volume & issue needed] In Xavier's conversation with Lilandra Neramani it's discovered that S.H.I.E.L.D. were former financiers before their falling out with Xavier; it is unknown what their intentions were.[volume & issue needed] The Church of the Shi'ar have become major investors.[volume & issue needed]
The mansion is purposely demolished by Iceman in "Ultimate Requiem". This is because the team had been devastated by Magneto's attack and the survivors were going on the run.
