Dump? Are you kidding? Do you realize where we are? This - this dump is the last true beacon of light in a world gone topsy-turvy. This dump is the epicenter of the ultimate chess match between good and evil.

The Men of Letters Bunker, or "the Batcave" as it was referred to by Dean Winchester, was the secret base of the Men of Letters. It could only be accessed by a special key.

History and details


Top View.

The Men of Letters bunker housed many artifacts and was located in Lebanon, Kansas, the geographic center of the contiguous United States. Construction of the bunker was started in 1932 and took three years to build. After it was finished in 1935, the first case investigated in the bunker was that of Dorothy Baum. Much of the events were written into a set of books by Dorothy's father, who was a Man of Letters himself.[1]

It was described as containing every object, scroll, and spell collected by the order for over a thousand years, as well as research and books on a variety of subjects. After eighty years the bunker had functional power and water supply and was also capable of providing some form of Internet connection.

It was said to be the "safest place on Earth, warded against any evil ever created."[1][2] The warding on the bunker was devised by Cuthbert Sinclair before he was expelled from the Men of Letters and went rogue.[3] The only way to get in was with the Key of the Order of Letters.[2]

The bunker also possessed a lockdown mode, which could be activated by a lever in the electrical room. Once locked down, no one could get in or out of the bunker. The process caused an alarm and all the lights to dim, and be replaced by red ones.

In 2013, it became Sam and Dean Winchester's new base of operations. It was impossible to track cell phone signals that came from within the bunker; the closest that one could get a signal was outside of a twenty-mile radius.  

The witch Olivette, revealed that there were actually many bunkers scattered across the world.[4] Arthur Ketch also calls it "a bunker" when talking to Dean rather than "the bunker", further showing that there are more bunkers elsewhere.[5] Sam later told Dean that the Men of Letters only had one bunker, but they had smaller chapter houses acting as outposts all over. The chapter house in Portsmouth, Rhode Island had a similar appearance to the bunker, but was much smaller.[6]

By earlier 2017, Sam had downloaded all of the bunker's files into an online archive for better accessibility.[7]

Later in 2017, the Bunker was put into a lockdown by Arthur Ketch that locked Sam, Dean, and Lady Toni Bevell inside, cut off all power and water and shut down airflow into the Bunker. This would enough to kill them in about two days. After being unable to find a magical way to reverse the lockdown, Dean used a grenade launcher to blast through a wall into the sewers and hit the manual override located outside the Bunker, ending the lockdown moments before it would've been fatal.[8][9]

In 2018, in an attempt to rescue Mary and Jack from Apocalypse World, the Winchesters opened a rift leading from the bunker into the alternate reality.[6] After twenty-four hours, the rift closed again on its own.[10]

After discovering that the archangel Gabriel was within the bunker, the Prince of Hell Asmodeus contacted Sam and threatened to kill him and destroy the bunker if Sam didn't turn over Gabriel. Asmodeus was able to break through the bunker's wards as they were not designed for a demon as powerful as him and led an incursion into the bunker with five other demons. In the battle that followed, the other demons were overpowered and ultimately killed while the Prince of Hell himself was incinerated by Gabriel in the middle of the bunker's main room.[10]

A rift to Apocalypse World was opened using a captured Lucifer who then supplied the needed grace to keep the portal open. Gabriel, Castiel and the Winchester brothers journeyed into the rift in order to rescue their mother and Jack. Rowena stayed behind in order to watch the portal, however Lucifer managed to escape his bonds was about to kill the witch, however she managed to knock him into the rift. Without the archangel, Rowena uses her magic to keep the portal as long as possible.[11]

In the other world, Dean and Sam reunited with Mary and Jack, however the two refuse to return to the Main Universe until Michael is defeated. The brother then entice the members of the resistance of returning to the main universe, using the bunker and its accumulated supernatural archives an weaponry as a lure in their goal in defeating Michael. Eventually all the members in the resistance agree to evacuate to the main universe. All members of the resistance and the Winchesters safely return to the bunker, save Gabriel, who sacrificed himself to stop Michael and Lucifer who was intentionally left behind by Sam. The refugees and the Winchester shared a toast to mourn those left behind.[12]

The bunker soon became a new home for the refugees from Apocalypse World. There Sam and Mary helped them assimilate to the main universe. Some like Charlie resumed their roles as active hunters. The bunker soon became a murder scene when one of the refugees Maggie was found dead outside in the forest. Later Lucifer appeared miraculously stating he wished to see Jack. However soon after he resurrected Maggie as a show of good faith, she revealed it was he who murdered her. Michael then appeared revealing the two had formed an alliance in order to invade the main universe.[12]

Three weeks after Michael possessed Dean after killing Lucifer, Sam Winchester has become the de facto leader of a new hunter network made up of the Apocalypse World refugees. The bunker that was used solely by the Winchesters has become a new base of operations for the hunters. More organized and structured, former resistance members have taken residence there, on the lookout for the archangel, but also continuing hunting monsters.[13] After Michael escapes from Dean's mind, he possesses Rowena and uses her body to kill Maggie and several other Apocalypse World hunters in the bunker's main room. However, using the power of his soul, Jack is able to exorcise Michael from Rowena and kill him, regaining his original powers through Michael's absorbed grace.[14]

There are hidden symbols in the frieze around the library, plus sigils and devil traps above the bookcases. At the bottom is a bronze devil trap. At every doorway, there is a symbol which would be the next line of defense if a demon broke in.

Layout and Contents


The Library.

The bunker was laid out in two layers, with a balcony level on the entrance, and a second level where the main area was. It also contained a library and was decorated in lavish style. The walls were covered with bookcases and filing cabinets, detailing many files collected over centuries, and included every exorcism over three hundred years, case files, incident reports, and information on hunters the Men of Letters worked with. At the end was a very large telescope. It also contained several storage rooms. There are hidden symbols in the frieze around the library, plus sigils and Devil's traps above the bookcases. At the bottom is a bronze devil trap. At every doorway, there is a symbol which would be the next line of defense if a demon broke in.

In the room adjacent to the library was a variety of old computers and machines, including "Commodore 64".[1] It was revealed they were still functional and possessed some form of sensors and early warning devices, as they were automatically activated when the angels were expelled from heaven and started tracking them falling, all over the earth.[15]

Sam and Dean discuss their plans inside the bunker.

It also had multiple showers and living quarters. The central area featured a long wooden table that could be used for gatherings. Much of the furniture and decor were from past decades. It had vinyl records and a functional record player. The headquarters also included many unique relics and artifacts, including the Spear of Destiny and the Key to Oz.[16]

Despite being a large building, its entrance was rather small and nondescript. The entrance was located near the road but was almost below ground level. One of the rooms that were meant as sleeping quarters was claimed by Dean Winchester as his own, and he decorated it with a series of guns and other weapons, including his blade from Purgatory on the back wall. The room contained a bed with a memory foam mattress and a desk with a reading light, against which Dean placed a picture of his mother.

The complex also housed a shooting range, complete with three targets[17] and a dungeon for holding demons hidden in one of its archive rooms. The dungeon included a Devil's trap as well as cuffs and chains that were engraved in spellwork.[18] There was also a very large kitchen, and what seemed to be a sick bay. 

The bunker had a garage that housed a lot of vehicles, like cars and Dorothy's motorcycle. Most vehicles were classics[1] due to the Order's foundation in earlier decades. After its discovery, Dean started storing the Impala here.[19] The bunker also had an electrical room which managed the controls to large parts of the building and included the lever that activates lock down mode.

The Bunker contains at least three pure gold knives that can be used to kill monsters.

The Bunker was warded for a long time by various spells, thanks to Cuthbert Sinclair's efforts,[3] rendering it near impenetrable to most supernatural attacks and invasion. These wards can be "powered down" by the inhabitants to allow beings such as demons to enter.[20]

Men of Letters Bunker Lockdown

The bunker on alert.

The Bunker can be sent into a lockdown that cuts off all power and water inside, locks the doors beyond any ability to open and stops the airflow into the Bunker. This type of lockdown will kill three people trapped inside in two to three days and with the addition of a mystical dampener, even magic can't reverse it. The only way to end this kind of lockdown is to hit the manual override located outside the Bunker.[8][9]

Supernatural Security Breaches

Even though the bunker is one of the safest places on earth, and supposedly "warded against any evil ever created", there were a few cases that supernatural creatures succeeded to break in (however, in all cases it was executed by beings of immense power):

  • In We Happy Few, Amara teleported in after she absorbed Donatello's soul and found out the bunker's location. The warding of the bunker were able to keep her out for a few moments, but she broke through them easily.
  • In Bring 'em Back Alive, Asmodeus and some of his demons broke into the bunker searching for Gabriel. Asmodeus was able to burn through the warding, possibly due to the fact he was powered up by Gabriel's grace.
  • In Let the Good Times Roll, Alternate Michael broke into the bunker while hunting down Sam, Dean and Castiel they escaped from him. As the most powerful known archangel (by his own power), his power allowed him to literally break through the bunker's warding.






  • Castiel's safe place inside his mind is the bunker's kitchen.
  • During Gadreel's possession of Sam, Sam was inside what he thought was the bunker's library.
  • In All in the Family, God teleports the Impala into the middle of the Bunker's storage room while saving its passengers from Amara.
  • As shown in We Happy Few, Sam's bedroom is Room 21.
  • Dean's room appears to be Room 11.
  • Room 15 appears to be a guest room, as Mary Winchester, Mick Davies and Castiel were each shown using this bedroom.
  • Fans who toured the Supernatural set of the Men of Letters bunker revealed that the crew use the same room as the set for Sam and Dean's bedrooms.
  • In The Vessel, Lucifer drapes Castiel's trench coat over a chair after getting it wet. He is banished away before he can retrieve it, yet he appears in the following episode with an identical one.
