[[File:TheCage.png|right|500px]] Lucifer's Cage is a prison located in [[Hell]], designed by [[God]] to hold [[Lucifer]] captive.
After [[Lucifer]] was banished from [[Heaven]] for defying [[God]], he twisted a human [[soul]] into the [[Lilith|first demon]]. After this, God sent [[Michael]] to imprison Lucifer in the Cage which was locked with 600 mystical seals .
In 1972, [[ Azazel]] possessed a [[ Father Lehne|priest]] at [[ St. Mary's Convent]] , and killed eight nuns in the chapel. This enabled him to speak to the imprisoned Lucifer. Lucifer tells Azazel that Lilith is needed to break [[ the 66 Seals]] that hold him captive in the Cage and that he needs to find a very "special child. "<ref name="four22">[[ 4.22 Lucifer Rising]] </ref> This leads Azazel to recruit [[ :Category:Special Children|select children]] , including [[ Sam Winchester]] and to set in motion events that subsequently lead to the breaking of the 66 Seals.
In 2008, after [[Dean]]'s return from [[Hell]], [[ Castiel]] reveals that Lilith is trying to break the seals that lock the Cage in order to free Lucifer . Dean later learns that the first seal was broken when he was in Hell, and broke under torture and began torturing [[souls]] himself. Sam continues clandestine missions with [[Ruby]], developing his powers even though this involves drinking [[demon blood]], believing that killing Lilith will stop the Cage being opened. [[Image:Luciferscage.jpg|300px|right|thumb|Sam/Lucifer and Michael /Adam fall into the Cage. ]] In 2009, Sam unknowingly releases Lucifer from the Cage by killing Lilith at [[ St. Mary's Convent]] . Lilith is revealed to have been the last of the 66 Seals. As Sam and Dean attempt to find a way to stop Lucifer and the impending [[Apocalypse]], [[Gabriel]] tells them that the [[Four Horsemen of the Apocalypse]] all own rings that together can reopen a portal to the Cage anywhere. After collecting all the rings, Sam comes up with a plan in which he will allow Lucifer to [[possess]] him, and then force him into the Cage . The initial attempt fails, but when Lucifer confronts Michael at [[Stull Cemetery]], Sam activates the rings and as the Cage opens, he manages to gain enough control to force himself (and Lucifer) into the Cage. [[Michael]] (in possession of [[Adam]]'s body) tries to stop him but is dragged into the Cage as well.
After the averted Apocalypse, [[ Raphael]] tried to reopen the Cage to release Lucifer and Michael, to continue where the angel' s plans lefy off, but was ultimately unsuccessful due to Castiel leading a civil war in Heaven to stop him. During this time, Sam is subsequently rescued from the Cage by Castiel , but his soul remained trapped in the Cage being tortured by Lucifer and Michael. [[ Death]] agrees to retrieve Sam's soul, and returns it to his body, setting up a temporary "wall" in Sam's mind to prevent the knowledge of the horrors that happened in the Cage from destroying him.
Following the release of [[the Darkness]], cries are heard coming from the Cage, and the demons speculate that Michael or Lucifer are trying to warn them about it. Sam also starts having flashbacks or visions of his torment in the Cage. When Sam finally journey's to Hell to confront Lucifer with [[Crowley]] and [[Rowena]], he learns that the impact of the Darkness' release had a massive effect on Hell, causing the Cage to become damaged. It was through those fissures Lucifer was able reach out and give Sam his visions of the Cage. Lucifer is eventually able to escape in [[11.10 The Devil in the Details]] by taking [[Castiel]] as his [[vessel]].
The exact location of the Cage was originally quite vague. It seemed to be of the same realm of [[Hell]], though obviously separate from the part of Hell where [[demon]]s are produced, as it took great effort for even [[Azazel]] to establish communication with [[Lucifer]]. [[Dean]] is able to open the Cage via the Horseman's rings in a deserted building and [[Sam]] uses them to open the Cage in [[Stull Cemetery]]. It was conjectured by fans that, since the Cage could be entered from multiple locations, it may exist on a different dimensional plane.
However, [[Sera Gamble]] later confirmed that the Cage is, "[http://featuresblogs.chicagotribune.com/entertainment_tv/2010/08/supernatural-season-6.html At the bottom of the lowest depths of the ninth circle of the worst bit of Hell.]" In season 11, the Cage is finally shown to be a box hanging by multiple chains surrounded by black storm clouds
. In [[11.09 O Brother Where Art Thou?]], Crowley confirms that the Cage's location is in the furthest reaches of Hell -- Limbo.

Castiel explains to Dean that if Lucifer ascends
to from the Cage, [[Hell]] and chaos will follow his presence on Earth. He later elaborates by saying that all of creation will literally experience Hell if[Lucifer roams Earth.
===[[4.16 On the Head of a Pin]]===
Castiel and Uriel ask Dean to torture [[Alastair]] to find out who is murdering angels. In the process, Alastair revels that it was Dean who broke the first seal of Lucifer's Cage.

===[[4.22 Lucifer Rising]]===
Sam and Dean get the final two rings after [[Castiel]] cuts off [[Pestilence]]'s finger using [[Ruby's knife]] and [[Death]] gives his ring to Dean in exchange for his promise to do whatever it took to free him from Lucifer's control, ensuring that Sam would jump into the Cage as soon as he consented to possession by Lucifer. Death also instructs Dean on how the rings work to open the cage, although the explanation is not shown in this episode. Dean is later shown working with all four rings on a table. They join together to form a triangular shape with [[War]]'s ring in the center and the other three rings surrounding it. When Bobby asks him about Death teaching him how the rings work, Dean responds, "Yeah, it's nuts."
===[[5.22 Swan Song]]===
Dean finally agrees to support Sam's plan though he has deep misgivings telling him, "Your Hell is gonna make my tour look like Graceland." Sam primes himself by drinking [[demon blood]] and then they confront Lucifer. Lucifer knows of their plan, but Sam says "yes" anyway. As Lucifer takes him over, Dean uses the ring and an incantation to open the "door" to the cage. However Lucifer is in control, and he easily closes it.
Later, in [[Stull Cemetery]], Lucifer faces [[Michael]] who appears using [[Adam Milligan]] as a [[vessel]]. Lucifer tries to dissuade Michael from the fight, blaming their conflict on [[God]], and suggesting they walk away. Michael counters that he must carry out God's orders, and that it's his destiny to kill Lucifer, who is evil. Just then Dean arrives in the [[Impala]], Def Leppard's "Rock of Ages" blaring. Dean tries to talk to Sam, inside Lucifer, but Michael tells him it's not his fight anymore. Castiel arrives and throws a Molotov cocktail made with [[holy oil]] at Michael, causing him to vanish temporarily. Lucifer turns and blows Castiel up with a snap of his fingers. Then, as Bobby begins shooting him, he snaps
Lucifer starts to beat Dean, taunting him, saying he will kill him slowly and make Sam feel it. Dean doesn't resist, just telling Sam he won't leave him. As
he goes to land another blow, he glances at the Impala, and suddenly all Sam's memories of life with Dean rush at him, allowing Sam to take control over Lucifer. He tosses the Horsemen's rings to the ground , recites the incantation to open the Cage. He and Dean look at each other one last time, but as Sam goes to throw himself in, Michael reappears. Michael tries to stop him, but Sam drags him into the chasm too, and it shuts.
===[[6.01 Exile on Main St.]]===
===[[6.11 Appointment in Samarra]]===
Dean has himself purposefully "killed" under medical supervision, so he can plead with [[Death]] to rescue Sam and [[Adam]] from the Cage. Death agrees to rescue only one of them -- Dean chooses Sam. Death makes a wager with Dean, that if he will wear Death's ring for one day, and perform his duties, then Death will rescue Sam's soul.
he tells Dean that he will be able to contain the part of Sam that will be damaged from his time trapped with Michael and Lucifer behind a "wall" in Sam's mind, although he can't guarantee how long this will maintain. Although Dean fails to wear the ring for a day, Death agrees to retrieve Sam's soul, which he returns to Sam.
Sam starts remembering a portion of events that happened when he lacked a soul. After Sam and [[Dean]] resolve the murders, Sam falls onto the floor, shaking uncontrollably, where he recalls some of the torture he endured in Hell by [[Lucifer]], where he is seen covered in flames.[[File:SamInHell.png|
