->''"Abandon all hope, ye who enter [[{{Hell}} here]]."''
-->-- Dante's ''[[Literature/TheDivineComedy Inferno]]''

There's a door ahead. Based on its appearance or its context -- usually standing there with no actual wall around it -- you just know something amazing and dangerous lies on the other side. This isn't just a physical trope of a door being there, but a narrative device. Because the door is so obviously doomful, the characters recognize that going through is a big decision.

Compare CoolGate, TheLonelyDoor, PortalDoor. Not to be confused with DoomDoors. Often a PointOfNoReturn in video games.



[[folder: Anime and Manga]]
* The Gate of Truth in ''Manga/FullmetalAlchemist''.

[[folder:Fan Works]]
* In ''Fanfic/MementoVivere'', a VideoGame/FinalFantasyX fanfiction, Rikku’s attempts to enter the Chambers of the Fayth turn them into this trope.

* The door to the maze in ''Film/{{Labyrinth}}''.
* ''Film/JurassicPark'': John Hammond deliberately invokes this by having the guided tour of the island begin by entering a large, impressive door, but it's more for show than anything.
-->'''Ian Malcolm:''' What do they keep back there, Film/KingKong?
* The entrance to Toontown in ''Film/WhoFramedRogerRabbit''.
* ''Film/KingKong1933'': The huge door in the wall surrounding the interior of the island.
* We get about [[LeaveTheCameraRunning five minutes worth]] of this in Creator/AndreiTarkovsky's ''Film/{{Stalker}}'', in which the main characters stare at an omnious door, contemplating whether or not they should go in.
* In ''Film/{{Spiral}}'', a frequent recurring motif is a glowing door in the background of Mason's apartment that has something to do with his [[spoiler:imaginary]] murders.

* The archway in the Ministry of Magic in the ''Literature/HarryPotterAndTheOrderOfThePhoenix''. [[spoiler:The result of going through is implied to be CessationOfExistence.]]
* [[Literature/TheChroniclesOfNarnia Narnia]] has a number of these, including one near the end of ''Literature/PrinceCaspian''. Played with in ''Literature/TheLastBattle'' - the 'door of doom' is just the door of a stable....
* The three Doors in ''Literature/TheDrawingOfTheThree'', the second book of Creator/StephenKing's Franchise/TheDarkTower epic. As in the trope description, the doors themselves appear quite normal; it's the fact that they're standing in the middle of a beach with no walls attached or any visible means of support, and that they appear to vanish when one walks around to view them from the back, that marks them out as magical.
* In ''Literature/HouseOfLeaves'', the door that appears in Navidson's [[color:blue: house]] after the family comes back from vacation, which wasn't there before.
* The door in Dante's ''Inferno'', with its famous [[StockShoutOuts (and much referenced and parodied)]] inscription "Abandon all hope, ye who enter here."
** Parodied in ''Discworld/{{Eric}}'', where the inscription has been crossed out in favor of "You Don't Have To Be Damned To Work Here, But It Helps!!!"
* In Creator/TherinKnite's ''Literature/{{Echoes}}'' (the first book), Adem is walking down a hallway full of closed doors he needs to open in order to find the antagonist [[spoiler:Brennian]]. He belatedly realizes that since he's in a dream, ''anything'' could be hiding behind the doors.
* The Doors of Durin (west gate of Moria) in ''Literature/TheLordOfTheRings''.
** As is the Dimholdt on the Paths of the Dead, especially in the film version.
--->"The way is shut. It was made by those who are Dead, and the Dead keep it. The way is shut."
* Subverted in ''Literature/ThePrincessBride'' (the book), where the actual danger lies ''on the door itself''.
* The entrance to the TempleOfDoom in ''[[Creator/MatthewReilly Temple]]'' was the Incan version: a giant rock blocking a passageway, with very detailed pictures of people dying all around it.
* When the miners of ''Literature/GalaxyOfFear: Spore'' DugTooDeep into an asteroid, they found a monstrously thick door with a terrified-looking statue outside of it. There had been more nuanced warnings there too, but those had been scraped away.
* Carl Sandburg "Rootabaga Stories" has a chapter "Four Stories about the [[AddedAlliterativeAppeal Deep Doom of Dark Doorways]]" but being a children book, no Doom whatsoever can be found. Probably just the DoomyDoomsOfDoom syndrome at work.

[[folder:Theme Parks]]
* The appropriately-named Gates of Doom in ''Ride/IndianaJonesAdventure'' at the Ride/DisneyThemeParks appears to be a portal to a nightmarish alternate dimension.

[[folder: Video Games]]
* Possibly the final door leading to Tabuu in ''VideoGame/SuperSmashBros Brawl'', being a gigantic glowing door leading to the final boss that requires you to defeat every opponent you've ever faced to pass through it.
* Both played straight and subverted in the ''Videogame/KingdomHearts'' series.
* The door that leads to the first boss in ''VideoGame/SilentHill3''.
* The red boss door in ''VideoGame/YoshisIsland''. Bonus for being twice the size for the FinalBoss.
** ''VideoGame/SuperMarioWorld'' did it first: Haunted Houses, Castles, and Boss Rooms all have some sort of doomy door.
** Not to mention the ''[[VideoGame/PaperMarioTheThousandYearDoor Thousand-Year Door]]''. The earth all around it cracks when it opens!
* The door leading to the Fugue plane in ''VideoGame/NeverwinterNights2: Mask of the Betrayer''.
* The Oblivion Gates in ''[[Videogame/TheElderScrollsIVOblivion The Elder Scrolls 4]]'' are big burning arches that scorch the area around them, turn the sky above it red and ominous, and the plants from Oblivion also grow around it too.
** Specifically, what is on the other side leaks over. Which is a barren wasteland of blackened islands in a sea of lava.
* The Dimensional Gateways in the VideoGame/{{Warcraft}} setting are these. The prime example is the Dark Portal that leads to Outland, a world that had so many of these gates opened that they tore the world apart and sent what was left into the Twisting Nether.
* ''VideoGame/GodOfWar'' has three main flavours of door: large, very very large, and "yeah, definitely a boss here" large. (Or, from a god's point of view, miniature, small, and medium).
* In ''Videogame/{{Minecraft}}'' both the Nether and End Portals. They don't look great like many other things on the list, but considering how the rest of the game looks, they're pretty hellish. Some people have even made their portal rooms the definition of this trope. Just look [[http://thezserver.webs.com/photos/Server-Slideshow-Photos/MinecraftNetherPortal.png here.]]
* ''Videogame/MassEffect2'' has the Omega-4 Relay, which is coloured red as opposed to the usual blue of the Mass Relays, almost like a warning, which is suitable, because ships that enter it never return.
* ''Videogame/{{Diablo}}'' has this in spades. Lets you go to hell with horrors at the other end.
* The door to Ultimecia's throne room at the end of ''VideoGame/FinalFantasyVIII'' is a red double-door with skull figurines above it and an all around creepy feel to it. Plus there's a Save Point in front of it. Touching this door gives you the chance to back off or open it, the latter of which starts the four-stage FinalBoss fight of the game.
* The door that leads to the Dead God's Pad in ''VideoGame/TheWorldEndsWithYou''. Shiki [[LampshadeHanging lampshades this trope]] by saying "This door just screams 'endgame.'"

[[folder: Web Animation]]
* The third ''WebAnimation/CharlieTheUnicorn'' flash has one of these. Er...sort of. It turns out that the door is not as fantastic and mysterious as advertised.

[[folder: Web Original]]
* The sequel to the Literature/NESGodzillaCreepypasta has a large gate that appears between stages, with seven empty slots that are gradually filled each time Carl defeats a boss. Presumably, it will open when all seven have been beaten.

[[folder: Western Animation]]
* ''WesternAnimation/{{Futurama}}'' has a ShowWithinAShow that uses this: The Scary Door.
* In ''WesternAnimation/TheRealGhostbusters'' episode "Knock, Knock", a literal Door of Doom is featured.
-->"''Do not open until doomsday!''"
* ''WesternAnimation/DangerMouse'' has DM knocking on "the Door of Doom" only to have it then fall off its hinges and flatten him and Penfold. Leading to this exchange:
-->Penfold: (giggling)
-->Danger Mouse: "Penfold, the Door of Doom has just fallen on us."
-->Penfold: "I know, chief!" (giggling)
-->Danger Mouse: "Then why are you giggling?"
-->Penfold: "Because Chief... [[IncrediblyLamePun You've just become a dormouse!]]"
-->Danger Mouse: "[[CatchPhrase Penfold. Shush.]]"

* The painting ''That Which I Should Have Done I Did Not Do'' (also called ''The Door'') is one of these. Subverted in that it represents a wasted life - ''not'' going through it was the wrong choice.
