Portal Door

This is a door that opens to a location other than the one behind it; in time, space, and even outside of it! This door may be a Cool Gate, but it can be of much more mundane make and manufacture.

How does this door bend space and time like a Dali painting? It may be a technological teleportation device, a Time Machine (or both). It could also be made through magic (which usually justifies it being otherwise mundane looking), and may lead to the Magic Land, Spirit World or Dark World. Lastly, it may be some form of "naturally" occurring gateway of Eldritch origin that leads to an Alternate Dimension.

See also The Lonely Door (which often overlaps, but 1) need to be a standard door, not just any kind of gate, and 2) leads to a room that looks as if it were inside a building even though there is no building in sight), Cool Gate, Portal Network, Portal Book and Portal Pool. Sub-Trope of Teleporters and Transporters.

  • Bleach: The Gate To Hell.
    • Bleach also had the senkaimon (a gate that looked like a big sliding door) that Soul Reapers could create to travel from the world of the living to the Soul Society (Captain Kuchiki uses one early in the series to return himself, Rukia and Renji).
  • One of Doraemon's recurring tools is the "Anywhere Door", which when walked through brings you to any location you tell it, as long as you made sure you worded your request carefully.
  • The door leading out of Howl's Moving Castle.
  • Done interestingly in Blue Exorcist, where the doors are completely mundane- it's the key that is used to open it which changes the location. This is a necessary system to get around True Cross Academy due to all the anti-demon traps.

  • A Crown Of Stars: Several portal doors leading to other dimensions show up as soon as the first chapter when Daniel opens one inside Shinji and Asuka's tent to pick them up and take them to Avalon. During their stay in Avalon, both teenagers found out that magic and technology capable to create or build inter-dimensional gates or time doors are commomnplace. Also, bad things happen when a portal collapses, leaving the main characters cut off and stuck on other dimension.
    Asuka’s rest did not last long undisturbed. Shinji was just rising from replacing his cello in its padded trunk when the sun rose in their tent.
    Shinji whirled around. “What?” He blinked his eyes repeatedly against the sudden blaze of gold. A perfect seven-foot circle of seeming daylight stood on the far side of the tent, filling the tent with noontime brightness. Shading his eyes with his hand allowed Shinji a slightly better look at it. Almost too bright to look at directly, it seemed for all the world like a floodlit pool stood on its side. Shinji had only a moment to stare in confusion when the light dimmed as a man stepped out of it. This did not diminish his puzzlement.
    “Pilot Ikari Shinji-san?” The man inquired in Japanese.
    “Third, what’s th—-” Asuka blinked awake in her suddenly brightly lit sleeping bag, then bolted upright. “Who the hell are you?! What is that?”
    “Fräulein Pilot Asuka Langley Sohryu? I’m sorry to interrupt your rest, but this is the earliest I could arrive.” Shinji still could hardly see the backlit figure, just a caped silhouette. The figure noted his squint. “Ah, my apologies for the brightness of the portal. Rather a large energy differential between here and home. Let me get that.” He snapped his fingers and the glowing mini-sun shrank to a point and vanished. The near-daylight illumination dropped to just the solitary camp lantern hanging at the tent’s entryway.
  • Weird Incident Shit has a portal window stuck on Problem Sleuth's door. It leads to Gensokyo.
  • Several of these appear in Adventures on the Friendship Express in the form of mirrors. Events and worlds shown on these mirrors include the ones from Sonic 3 And Knuckles, Sonic Spinball, My Little Pony And Friends, Sonic Lost World, Sonic Boom and My Little Pony: Equestria Girls.

  • The Matrix Reloaded. The doors that can open to different locations depending on which person or key opens them.
  • Done in Monsters, Inc. with the doors that serve as portals from the monsters' office building to the bedrooms of children they're supposed to scare.
  • Beetlejuice. Following the instructions in a book, the ghostly protagonists use chalk to draw a door on a wall, open it and walk through it into the afterlife bureaucracy.
  • Likewise in Pan's Labyrinth, in which Ofelia uses a piece of magical chalk to create a door to the Pale Man's realm.
  • In The Adjustment Bureau, the Adjustors use any door to travel to any other door.
  • The Rift from Pacific Rim.
  • Blink from X-Men: Days of Future Past has the mutant power to create these at will.
  • The Return (1980) has the portal in the back of The Prospector's mine which may lead back to the alien homeworld.

  • Dan Simmon's Hyperion Cantos overcomes the problem of space travel and communication with two different systems. The space travel system is essentially portals. Some very wealthy homes consist of rooms on different planets connected by these portals.
  • In Neil Gaiman's Neverwhere (book and show), Door and her family can open up doors anywhere. Their home is a bunch of unconnected rooms.
  • The door in Dan Abnett's Ravenor, a plain wooden door that opens through space and time. Originally, it used by special trained operators, to let the questions of those who came to them direct it; when the house was broken, Ravenor operated it to put his powerful psionic abilities into play.
  • Susan Cooper's The Dark Is Rising series. Powerful Old Ones (such as Merriman Lyon) are able to summon a magical gate (which looks like a pair of doors) that allows travel through time and space.
  • John DeChancie likes this trope; his Castle Perilous has 144,000 doors, each leading to an Alternate Universe, and they don't just wait for you to walk through—the portals wander, and actively seek out those who want to travel or get away. His Skyway series has "Tollbooths" (no doubt named as a Shout-Out to The Phantom Tollbooth) which use miles-tall columns of virtual particles to create wormholes linking a vast Road across thousands of planetary surfaces.
  • In The Redemption of Althalus by David Eddings, the protagonists live in a house with as many rooms as they like, as large as they like (they occasionally have armies on the march through the corridors) and can open doors to literally anywhere on command. One of the protagonists attempt, out of curiosity, to open a door to "nowhere"—although they avert the attempt before they succeed, the concept is enough to freak out their patron goddess something fierce.
  • The door leading out of the title castle in Diana Wynne Jones' Howl's Moving Castle.
  • The redstone doorways in The Wheel of Time look like empty doorframes, but walking through one will transport you to a dimension populated by weird aliens who see the future or grant wishes.
    • The Wheel of Time has them in at least three flavors: the aforesaid redstone doorways, the Waygates built of finely carved white stone and having nice reflection visual effect, and the One Power-created Gateways for Skimming (travel via subspace) and Traveling (instant teleportation).
      • There are also Portal Stones, which are Exactly What It Says on the Tin. They link not only to other portal stones in the world, but also to Portal Stones in Parallel worlds. Very handy, if not well understood at all.
  • The title tollbooth of Norman Juster's The Phantom Tollbooth.
  • The Forgotten Door by Alexander Key. An inter-dimensional machine/gate.
  • The appropriately-named Gates in Mercedes Lackey's Heralds of Valdemar series. They have a number of important limitations, in that they are single-use constructions created by a powerful mage using his own life force, and can only go somewhere said mage has been to and knows well. The ancient Adepts of the Mage Wars, as well as the mysterious Eastern Empire, on the other hand, knew/know the secrets of Permanent Gates, which once created are simple to activate and use.
  • In Patricia A. McKillip's The Bell at Sealey Head, Emma keeps opening doors and finding Princess Ysabo. She never dares go in for fear that she can't come back. And one day when she opens the door to her grandmother's room, it shows the princess in a different room. She closes it, reopens it, and finds her grandmother's room.
  • The aptly-named Gate, which was opened by a goddess of a Low Fantasy world, straight into the heart of Ginza, Tokyo.
  • The Green Door in H. G. Wells' short story of the same name.
  • One means of getting around in the endless world of The Neverending Story is The Temple of a Thousand Doors (Der Tausend-Türen-Tempel), which contains an infinite number of five-sided rooms with three doors each. Every door different in colour, shape, material etc. To get to the place you wish to go, you only need to pass through the rooms until you find the door that reminds you strongest of the thing/place/person you're looking for. This may take some time.
  • The portable door in The Portable Door by Tom Holt. A door-shaped sheet of something that can be rolled up, but when put against a wall will open to the desired location.
  • In Stephen King's The Dark Tower, Roland discovers a series of doors which allow him to look into other worlds, possess a specific individual on the other side when he steps through the door, and pull that person back through the door into his own world. This is how he eventually gathers his three traveling companions who follow him in the later books.
  • Doors that open to distant locations, times, and/or realities are a dime a dozen in the Nightside series, and one minor character even operates a business where people can pay to pass through any of the hundreds of Cool Gate doorways he's stocked his shop with.
  • In the last volume of Labyrinths of Echo, Max and Melifaro end up in a magical reality where all doors are this for them: stepping through any kind of portal or door (even self-constructed) transports them to another world (seemingly) at random. When they finally make it back to Echo, Max discovers all doors still continue to function like portals to random universes for him, so he has to condition himself to check every doorway he passes through for this effect.
  • In Harry Potter and the Order of the Phoenix during the battle in the Department of Mysteries, Sirius Black gets pulled into an ominous veiled archway after being cursed by Bellatrix. And he hasn't been back since...

  • Professor Chronitis's time-traveling study in Dirk Gently's Holistic Detective Agency appears as a door in a convenient wall, or cliff face.
  • In Rebecca Lickiss's Eccentric Circles, Grandma Dickerson's house leads to a Magical Land.
  • In Sergey Lukyanenko's The Boy and the Darkness, each world has three such doors that link it to a parallel world. In the novel, the Sunny Kitten takes Danny through one such door to a world perpetually covered in darkness. The door promptly gets destroyed by the Flyings. Danny manages to find the other two doors, but they get destroyed as well, leaving him stranded in this world. He has a final chance to return to his own world but sacrifices it to save his friend. Finally, the Sunny Kitten explains that the doors directly to Danny's world are gone, but there are other doors leading to other parallel worlds. Thus, they may be able to find a door to Danny's world there.
    • In Lukyanenko's Rough Draft duology, the protagonist is put in charge of a Warp Zone with several doors, each one leading to a different world. Throughout the duology, he meets several other "customs officers", whose places of residence feature doors to different worlds.
  • In Chronicles of the Kencyrath, within The Master's house, there are portals to all of the worlds that the Kencyrath had to abandon in their flight.

  • The Key in The Lost Room can turn any door with a tumble lock into this, which is why Karl Kreutzfeld made sure all the doors in his home were of the sliding variety (he forgets about the door in his son's fake castle and another one covered by drywall). Technically, though, each door opened by the Key leads to the titular room, at which point the holder of the Key can open the room's rood to whatever location he can envision.
  • The Star Trek: The Original Series episode, "All Our Yesterdays" has the Atavachron, a machine that creates a portal door/wall to a time in that planet's past.
  • Pictured is the Iconian doorway from Star Trek: The Next Generation. It has no apparent limitation to range, and at times opened to the Enterprise-D and the Romulan ship also in orbit. Another appeared in Star Trek: Deep Space Nine under control of a rogue Jem'Hadar faction.
    • In the original Trek there was one of these called the Guardian of Forever. Goes pretty much anywhere and anywhen, has a mind of its own. Despite the similarities, no canon connection exists between it and the Iconian gateways (In fact, it claims to be 'its own beginning and end,' and is billions of years old. The Iconian ones aren't quite that badass.)
  • In The Librarians, Jenkins uses the few magical artifacts he has in the Annex to build a "back door", a portal that connects a broom closet door to another door anywhere in the world. However, navigation is not easy and requires the use of sympathetic magic. Jenkins claims that it's a good thing he can even hit the target city. This allows the titular characters to travel the world without spending hours flying or driving. Unfortunately, it also leaves the Annex open to anyone who might stumble on the door from the other end (such as Morgan le Fay). Also, the pilot episode showed the Library itself having multiple doors leading to other parts of the world. In fact, the elevator that led to the Library was itself a portal, since the Library doesn't exist in our dimension.

  • Varkon features a stone gate through which Varkon can be seen. Playing well on the main table allows players to attack Varkon on the other side.
  • The "transphazers" of TX-Sector, which are used to teleport pinballs across the playfield.

    Tabletop RPG 
  • Planescape has Sigil, the City of Doors, which is pretty much made of this trope, though all "bounded spaces" can be portals, so not all the portals in Sigil are actual doors.
  • The Lords of Gossamer and Shadow RPG is even more focused on this trope than Sigil. All the Doors in the game are actual doors, connected to an endless staircase called the Grand Stair.

  • The Legend of Zelda: Twilight Princess features accessing The Temple of Time through a door with a black-and-white entry. This is extremely out-of-place, because the only other time the black-and-white happens in the series is in The Wind Waker when initially traveling to Hyrule.
