->''"Isn't space on a space station kind of at a premium? What's the big corridor down the middle of it for?"''
-->-- '''WebVideo/{{Unskippable}}''' on a corridor that a space battleship is flying through in ''VideoGame/{{Vanquish}}''

A tendency of SpeculativeFiction pictures and art direction to have interiors much larger than would be needed in reality. As in what could be a large room becomes huge and cavernous. Sometimes the story tries to justify this, claiming the {{Phlebotinum}} needs this much empty space to work, but usually it's just because BiggerIsBetter (or because the higher the ceiling, the more stuff there is to drop down on the escaping heroes when the [[CollapsingLair building collapses]]).

Usually it's so big, that if it was done in live action, it would be too expensive to do it as a set, or even [[ArtisticLicensePhysics architecturally impossible]]. Miniatures, matte backgrounds, or CGI would have to be used.

This can [[TruthInTelevision actually happen in nature]], as spelunkers can attest, but even in Speculative Fiction art, this can be exaggerated.

Note that "Unnecessarily" is in the title for a reason. If there is an actual practical need for it to be that large, it doesn't count. The Galactic Senate building, in ''Franchise/StarWars'', is not an example, because it's obviously to hold all of the senators from the many sectors of the Republic, sort of like a sports stadium. Neither is the RealLife Vehicle Assembly Building in Florida. It's large enough to have clouds form inside it on humid days, but it does have the purpose of building rockets, which need that much space.

Often associated with [[CreepyCathedral Catholic Cathedrals]]. May involve a MileLongShip or even a PlanetSpaceship.

[[folder:Anime and Manga]]
* ''Manga/{{Blame}}'' is a manga ''set'' in a never-ending series of ridiculously large superstructures. This is more-or-less {{justified|Trope}} in-universe, as the machines responsible for constructing TheCity have been doing so unguided for countless millennia. [[http://static.tvtropes.org/pmwiki/pub/images/whoa.png This]] conversation is held in a "room" that encompasses roughly the ''entire diameter of Jupiter''. [[spoiler:Because that's where Jupiter used to be before it was ''swallowed up'' by TheCity, only to be consumed for building material.]]
* ''Manga/{{Bleach}}'':
** Las Noches is large enough to have its own sky, and extremely large towers. It's also literally the only building in that dimension, so it's not like they didn't have the space to do whatever they wanted.
** Xcution hang out in an apartment building where thirty-six adjacent rooms on six different floors had the walls and ceilings between them torn out to make one giant room ("One of our members is kind of rich."). There's nothing in it except for a bar, some chairs, a couch, and a coffee table. Anything that would actually need that kind of space they do in a PocketDimension one of their members accesses.
* Kim's house in ''Anime/GhostInTheShell Innocence'' includes several large rooms including an enormous Music box style room and a great hall that appears to be outdoors. It's left deliberately ambiguous whether it's a real place or completely in virtual world.
* Gendo's office in ''Anime/NeonGenesisEvangelion'' is enormous, and the only thing in it is his desk. There's no possible reason for it to be this big, other than what appears to be a large Kabbalistic/occult diagram on the ceilings or walls. Fanon has it that space is at a premium in Tokyo-3, and this is all his understated way of showing off and intimidating.


* ''FanFic/HarryPotterAndTheMethodsOfRationality'': When Draco, Harry, and Hermione become generals of the student armies, they are given their own private offices. Draco and Harry find them bizarrely huge, with Draco unable to think of any reason for their size other than to show off the generals' status, and Harry not even thinking of that. It doesn't occur to either of them that they might be meant to use that space to meet with their advisors, because it doesn't occur to them that they might want to ''have'' advisors. Hermione, understanding their psychology, had her officers' chairs removed for her meeting with Draco.


[[folder:Films -- Animated]]
* ''WesternAnimation/MonstersVsAliens'':
** Gallaxhar's ship is, for no readily apparent reason, sized to fit a [[AttackOfThe50FootWhatever nearly 50 foot tall woman]]. The hanger bays have giant robots that need the room but the rest of the ship has a ridiculously spacious interior despite the fact that the corridors leading to it cannot fit the robots and it's doubtful "rampage by giant woman" was taken into account when the ship was built.
** A justified example is the monster holding facility in [[{{Area51}} Area 52]]. It was meant to house thousands of monsters of various sizes. The "unnecessarily" part comes from the fact that it never seems to house more than a handful at any given time. It would be necessary for any time they wanted or needed to move Insectasaurus.
* The vault where the doors are stored in ''WesternAnimation/MonstersInc'', which is larger than the rest of the factory put together ([[http://1.bp.blogspot.com/_7T9xWTmNPhI/S7zEv4j3ZMI/AAAAAAAAC6I/9Mat2UMjFRs/s1600/vlcsnap-147842.png See here]]). Sure, there's a lot of doors, but there's also a lot of empty space. The whole structure could be at least half the size if doors were stored in the middle and not just along the walls.
* This shows up occasionally in the Franchise/DisneyAnimatedCanon films, specially fairy tale-themed features.
** ''Disney/{{Cinderella}}'' has the King's Palace with very high ceilings in rooms and corridors. Despite the downgrade in animation, ''Disney/CinderellaIIDreamsComeTrue'' and ''Disney/CinderellaIIIATwistInTime'' still show this.

[[folder:Films -- Live-Action]]
* The dwarven city of Khazad-dûm in Jackson's ''Film/TheLordOfTheRings: The Fellowship of the Ring'' seems to consist of huge empty spaces with free-standing stairs on the edges and straight across. The book has mostly corridors and normal-sized rooms, with a few great halls. In general fantasy fiction, [[OurDwarvesAreAllTheSame dwarves in general]] tend to build things on an incredibly large scale; maybe they're compensating for something. The [[Franchise/DisneyAnimatedCanon Hi-Ho Song]] sounds better with an echo.
** The giant halls also prove to be a major issue when the dwarves unleash an EldritchAbomination: the Balrog. The great halls allow it to move about with relative ease, seeing as how it's twenty times bigger than the whole Fellowship put together. The {{Literature}} of Creator/JRRTolkien suggests that the dwarves had trouble with honkin'-big dragons as well: Smaug from ''Literature/TheHobbit'' being obvious, but also Scatha the Wyrm, and other cold drakes.
** Taken to an even greater extreme with Erebor in ''Film/TheHobbit'', where the interior seems to consist largely of bridges and platforms supported by stone colossi, presumably because there was a whole extra dimension going to waste otherwise. It really benefits Smaug, who can fly inside the dwarf hold despite being twice the size of a Boeing 747.
* Some leftovers of the Krell civilization in ''Film/ForbiddenPlanet''.
* The cavernous catacombs in the ''Film/{{Hellboy}}'' movie.
* Parts of the Black Fortress in ''Film/{{Krull}}''.
* [[AbsurdlySpaciousSewer The sewers]] in ''Film/TheMatrix'' are big enough to comfortably fly around in with airships.
* Appears in ''Film/SkyCaptainAndTheWorldOfTomorrow''; apparently the director kept requesting that the backgrounds be bigger, and since everything in the background was {{Chroma Key}}ed, this was possible.
* Occurs throughout the ''Franchise/StarWars'' franchise:
** Huge, tall shafts in both Death Stars in ''Film/ANewHope'' and ''Film/ReturnOfTheJedi''. They're practically BottomlessPits. The first film's {{Novelisation}} by Creator/AlanDeanFoster attempts to HandWave them as being part of the Death Star's ventilation system.
** The cavernous core of Cloud City in ''Film/TheEmpireStrikesBack''. Note that if you wanted to have an actual "Cloud City" in a gas giant's (or rather Venus-like) atmosphere, this would be the way to go -- basically, you would have the whole city as one huge airship floating far above the surface with little work needed to maintain it (and without explosive decompression/implosive? compression if you get a rupture in the hull, not to mention not having to use such strong materials in the first place). Obviously though, Cloud City from ''SW'' wasn't built like this (open views and active propulsion to maintain altitude) ...
** TheBridge of the Republic cruisers in the first ''[[WesternAnimation/StarWarsCloneWars Clone Wars]]'' series.
** The hangar bay next to the Senate building (Where Anakin and Obi-Wan land after rescuing Palpatine) in ''Film/RevengeOfTheSith''.
** In ''Film/RogueOne'', [[spoiler:Darth Vader]]'s fortress on [[spoiler:Mustafar]] has a huge, all-black chamber with a central platform suspended over a BottomlessPit... where a single guest is entertained for a two-minute conversation. In fairness, visitors are likely ''strongly'' discouraged.
* ''Franchise/StarTrek'':
** In ''Film/StarTrekTheMotionPicture'', there's huge rec room, with a ceiling at least two stories higher. There are catwalks running around the sides on what would be the second level. It also doubles as meeting/conference room, where the bulk of the crew meets for [[TheCaptain The Captain's]] mission briefing. Most other incarnations simply have mission announcements done from the bridge via the P.A. system. This room might actually serve a psychological purpose rather than a strictly practical one, by giving the crew somewhere to spend their downtime that's open enough to alleviate any feelings of claustrophobia, as well as look impressive when hosting foreign dignitaries for diplomatic functions.
** Starfleet ships in the reboot ''Film/StarTrek'' movies. The use of real world locations like the National Ignition Facility as filming sets results in the impression that the ship interiors are mostly empty space. Jefferies Tubes have been replaced by catwalks. The ''Enterprise'' even has a huge multi-story atrium that serves no apparent purpose other than RuleOfCool.
* In ''Film/TheGreatDictator'' Hynkel's office is gigantic. He uses this to his advantage by forcing Napaloni to cross this massive space as psychological intimidation. [[CrowningMomentOfFunny Napaloni comes in the room from a door right behind Hynkel's desk.]]
* KGB General Gogol's office in the ''Film/JamesBond'' movies.
* ''[[Film/TheMummy1999 The Mummy]]'' (1999): As in the ''Film/SkyCaptainAndTheWorldOfTomorrow'' example above, the director of the first two movies, Stephen Sommers, inspired the visual effects artists to come up with "The Stephen Sommers Scale". It goes: "1. Reasonable. 2. Ridiculous. 3. Oh my god, the computer is crashing. 4. What Stephen wants."

* From Douglas Adams: ''Literature/LifeTheUniverseAndEverything'' has Agrajag's shrine to Arthur Dent, which looks just like it was carved out of the inside of a mountain. Because it was.
* In Creator/MaryGentle's ''Orthe'' series, Golden architecture in general seems to have been made of this trope, which is made much more explicit in the second book, ''Ancient Light''. Like Creator/HPLovecraft (whom see), Gentle uses 'cyclopean' in reference to this kind of architecture. The Emperor's throne room, seen in flashback, is poorly lit, so that someone standing in it "cannot see how high the walls are, or how far above is the ceiling of this great hall." It contains "great pillars; yards in circumference, vanishing up into darkness".
* Paul's throne room on Arrakis in Frank Herbert's ''Literature/DuneMessiah'' is unnecessarily large for the sole purpose of intimidating his visitors. The author also describes how the room gradually gets smaller as you approach the throne to create the illusion that Paul is larger than he is.
* Whenever Creator/HPLovecraft uses the term 'cyclopean', look out for this trope. Used this in flashback in "Literature/TheShadowOutOfTime", with bonus BottomlessPits.
* In GRR Martin's ''Literature/ASongOfIceAndFire'', the Alchemists' Guild has a grand hall filled with green [[GreekFire wildfire]] torches. Tyrion notes that the hall is only used to impress visitors and all the torches will be extinguished as soon as he leaves.
** Also a staple of Harrenhal's design, a white elephant that was build to be in every way larger and most impressive then all other castles. Its kitchens are said to be as large as Winterfell's great hall, and its great hall large enough to entertain an army. Its justified as the ruins were originally a massive fortress city for the Harren the Black to lord the Riverlands in, and can sustain a large army for years.
* ''Literature/{{Discworld}}'':
** In ''Discworld/InterestingTimes'', the throne room of the Agatean emperor is described as indicating to all viewers "look at me, I can afford to waste all this space".
** This is {{lampshaded}} in descriptions of Death's residence, which the AnthropomorphicPersonification forgot to make the same size on the inside and the outside. Death made the rooms in his house into mile-long cubes (from the outside it's quite a normal size for a house), but because this is such a mind-boggling size for a room, humans like Albert (Death's housekeeper) mentally blot out the excess space, arranging the necessary furnishings on little patches of floor the size of normal rooms. As Death's residence isn't a part of the real world, this mental block works so well that Albert can step through the door of Death's office and ''instantly'' appear on the patch of carpet in the vast chamber's center, never actually setting foot on the intervening half-mile of floor.
** In ''Discworld/LordsAndLadies'', it is noted that Lancre Castle, home to a small royal family and handful of servants, is about the same size as Lancre Town, which contains a hundred cottages, and no-one really knows why.
* An Imperial officer in the ''ComicBook/XWingSeries'' meets the current head of the Empire in her quarters and lampshades this when he sees that they are both spacious and quite spartan, not ornate or filled with expensive stuff like he'd have thought. He then realizes that on Coruscant, a densely packed CityPlanet, having a lot of wasted space is a good way to show off your wealth, power, and prestige.
* Many of the House on Ash Tree Lane's rooms in ''Literature/HouseOfLeaves'', notably the Great Hall (of which none the walls except the one with the entrance door in it were ever actually reached) and the Spiral Staircase (which, [[ChaosArchitecture at its longest]], would have burrowed clean through the earth and extended 3,000 feet out the other side had the House not been an EldritchLocation that was BiggerOnTheInside). Especially since the rooms are entirely featureless and have no discernible purpose, so even the narrowest corridors are ''technically'' unnecessarily large.
* A mild example in ''[[Literature/HonorHarrington Mission of Honor]]''. Manticorians boarding captured Solarian ships are impressed -- not favorably -- by the size of some interior spaces, which are half again what Manty warship designers provide for the same function. But the Solarians haven't fought a real war for centuries.
** Note that this mainly applies to larger ships (superdreadnoughts, dreadnoughts, maybe battlecruisers), since the Battle Fleet has a more ceremonial/intimidation role. The Frontier Fleet ''has'' engaged in numerous localized conflicts, which is why its (smaller) ships are actually more cutting edge. Still no comparison to Manticore, though.
* In a similar vein, alien characters in ''[[Franchise/StarTrekExpandedUniverse Star Trek]]'' novels are often struck by how roomy, well-lit, and ''carpeted'' Federation vessels are. Reactions vary, but the visitors tend to be either a) [[ProudWarriorRaceGuy amused]] by the humans wasting their space and power on such things, b) [[BenevolentAlienInvasion relieved]] that they're doing that and not putting more guns on the ships instead, or c) [[AwakeningTheSleepingGiant worried]] that they might ''stop''.
* The AlternateHistory novel ''Literature/{{Fatherland}}'' briefly shows us Berlin as envisaged by Adolf Hitler and Albert Speer, as described in RealLife below. ([[HandWave Apparently they overcame the logistical and engineering issues somehow or other.]]) The protagonist, a war veteran turned homicide detective who's becoming increasingly disillusioned with the Third Reich, hangs a bitter lampshade on the fact that his government is blatantly CompensatingForSomething.

[[folder:Live-Action TV]]
* The underground chambers on Epsilon III in ''[[Series/BabylonFive Babylon 5]]'' were a deliberate {{homage}} to the Krell machine in ''Film/ForbiddenPlanet''.
* The secret underground bunkers of the Genii on ''Series/StargateAtlantis''.
* In the ''Series/DoctorWho'' story ''[[Recap/DoctorWhoS14E1TheMasqueOfMandragora The Masque of Mandragora]]'', Sarah Jane stumbles upon the Doctor's "boot cupboard", a massive room which has one pair of boots in it. When Sarah points out how absurdly large it is, the Doctor replies, "I've seen bigger boot cupboards."
* In ''Series/TheXFiles'' episode "The Walk", a hospitalized soldier attempts to boil himself alive in a hydrotherapy tank to escape an astral projection that's been tormenting him. The hydrotherapy room's cavernous ceiling disappears off into the darkness and the floorspace could have matched off against a small cathedral, even though there's only one hydrotherapy tank (which is essentially a smallish hot tub). The hospital is otherwise completely normal in appearance and the MonsterOfTheWeek has neither the means nor motive to distort the room itself, so this can probably be chalked up to RuleOfCreepy.
* Maleficents Castle in OnceUponATime has huge halls. Justified as Malifecent needs this space if she turns ino her dragon form.

[[folder:Tabletop Games]]
* The interior of most Imperial vessels in ''TabletopGame/{{Warhammer 40000}}'' resemble cathedrals. Really, really big cathedrals, with GothicPunk skulls and eagles everywhere.
** Just the fancy parts where all the important people like captains and navigators work. The rest of the crew is stuck with tiny dirty cabins under the engine room, if they're lucky, or sharing a room like that with 20 other people.
*** So not unlike a modern-day warship or submarine then. Only, y'know, we in the modern-day navies don't have to deal with Hrud monsters under the floorboards.
** On Holy Terra there is the Eternity Gate, a colossal chamber leading to the Sanctum Imperialis, where the Emperor Himself sits atop the Golden Throne. The Gate lies at the end of a mile-long aisle, the gargoyle-covered roof hangs half a mile overhead past clouds of incense and swarms of fluttering Cherubim, and the thousand steps leading to the portal take pilgrims through a forest of banners and standards from warriors over the past ten millennia. The Eternity Gate itself is large enough to accommodate HumongousMecha, while the Imperial Palace it stands in covers all of the Himalayas.
*** Eternity Gate is ''guarded'' by the two HumongousMecha -- two Warlord Titans from the famous Legio Ignatum stand an eternal vigil at its sides. And [[PraetorianGuard Adeptus Custodes]] unit standing guard in the Gate's hallway is said to consist of 10 000 [[UpToEleven super]]-[[SuperSoldier supermen]]. You ''need'' all that place to just fit all that forces.
** Holy Terra as a whole is made of this trope, mostly. The Ecclesiarchal Palace, for example (contextually equivalent to the St Peter's Basilica example above) covers an entire continent (Australasia, to be precise) with a single contiguous structure. It's avoided by a number of other structures, such as the Hall of the Astronomicon, which is what you get when you hollow out and structurally reinforce Mt Everest, then fill it with cells and living quarters for the most powerful telepaths humanity can provide. The actual Hall itself takes most of the available volume inside the mountain, and is a single room stuffed, from top to bottom, with psykers, life-support systems and psychic amplifiers.
** It's [[InvokedTrope invoked]] in both fluff and the literature whenever you have the POV of an average human in an Adeptus Astartes vessel/building: everything looks to be oversized, too tall and too wide and just generally too big... Then you remember it was built to scale for a genetically engineered SuperSoldier sub-race who stand 8 or so feet tall ''before'' putting on PowerArmor that's also about five and a half feet wide at the [[ShouldersOfDoom pauldrons]]. The oversized nature is one of necessity, and several passages show the opposite end of the spectrum, Space Marines (both in armor and out) struggling with the "cramped" sections that would be minor inconveniences for normal people.
* In general, tabletop games where combat is played out on a grid tend to feature buildings, furniture, and animals that are bigger than you'd expect, either to enable more different tactical movement options or to round up to the nearest number of units on the grid. This leads to phenomena such as chairs that are always spaced at least 5 feet apart from each other, horses that are 10 foot cubes, and simple peasant shacks that are 100 by 100 feet.

[[folder:Video Games]]
* Like the Tabletop example above, most video games with a free camera will have even supposedly humble cottages and claustrophobic caves that are actually huge [[CameraScrew so as to avoid the camera hitting things all the time]]. This is less prevalent in first-person views, much more so in third-person.
* ''VideoGame/HalfLife'':
** The Citadel from ''VideoGame/HalfLife2''. Although it does hold Striders, Gunships, Razor Trains and other tools of oppression, most of what you see are colossal empty rooms with no discernible purpose.
** The Black Mesa facility is very overbuilt, though the necessities of [[ForScience Science!]] mitigate this a bit. Black Mesa features a wealth of BottomlessPits and absurdly large rooms of dubious utility, particularly in the places the tram-lines run through, and deserves special mention for its truly gargantuan bio-dome enclosures and numerous [[AbsurdlySpaciousSewer cavernous sewers]]. Black Mesa is a decommissioned ICBM launch facility: it's probable that, similar to the rocket hangars at Cape Canaveral, all the huge amounts of unused space in the building were once used for storing enormous atomic missiles.
** In ''VideoGame/HalfLife1: Blue Shift'' the training level for the security guards (apparently one must get used to the body armor) is half a mile long, easy. For as large as Black Mesa is, if you [[http://www.nextdimension.org/bmrf/Black_Mesa_Research_Facility_HL_Map.jpg map out the facility]] (warning: HUGE image), you'll notice some interesting things; for instance, the big sludge pit in "Blast Pit" is mere ''feet'' away, on the other side of a wall, from the test chamber where everything goes wrong.
* The Aperture Science Enrichment Centre in ''VideoGame/{{Portal}}'' is very overbuilt, though the necessities of [[ForScience Science!]] mitigate this a bit. The test chambers are multiple stories tall, and the already unnecessarily large room that houses [=GLaDOS=] is in the center of a yet larger room whose dimensions are too great to see to the other side of. Then in ''VideoGame/{{Portal 2}}'' it's revealed that's only one part of Aperture Science Facility as a whole. The main testing area is a massive modular series of ever shifting panels connected by catwalks and lifts, containing manufacturing facilities and assembly plants for the testing chambers, as well as a ''[[ILoveNuclearPower nuclear reactor]]''. The Incinerator, which was just a hole in the ground in the first game, is revealed to be the size of a cathedral. The maintenance tunnels are massive, and the lower portion of the enrichment center is filled with layer upon layer of abandoned "Science Spheres" (the precursors of the modular Test Chambers), stacked one on top of the other in 9 colossal shafts. They even use enormous hatches the size of a small house to block off perfectly ordinary doors (though that last part [[RuleOfFunny was just a visual gag]]).
* Everything the Forerunners ever built in the ''Franchise/{{Halo}}'' series.
* The underground lab the "Hollow Bastion" area of ''VideoGame/KingdomHeartsII''. There are large unfurnished rooms scattered around the hallway which seem to serve no purpose whatsoever. In the same game, [[spoiler: Organization XIII's castle in The World that Never Was. Sora does not come across a single room of any practical purpose in his route through the castle, almost all of which have incredibly high ceilings and open areas, and most of them seem to be just places for Nobodies to spawn and attack Sora. Even the elevator is needlessly large, and there is no object in the castle which requires such an elevator to transport.]] In ''VideoGame/KingdomHearts358DaysOver2'', [[spoiler: it is shown that the castle has some practical rooms such as bedrooms for each member as well as a library and computer room, but no explanation was ever given for the large, open rooms seen in Kingdom Hearts II.]]
* In ''VideoGame/PrinceOfPersia2: The Shadow and the Flame'', level 11, the [[TempleOfDoom second temple level]], is built around an extremely high room. How high is it? After opening the level exit, to reach it one must make a running jump across the room, sending a [[TemporaryPlatform loose tile]] plummeting ''21 floors down'' to weight down a switch. This is after climbing floor by floor up from the bottom and passing over the room's ceiling.
* You see this kind of thing ''everywhere'' in ''VideoGame/SecondLife'', in part because realistically-scaled rooms and corridors [[CameraScrew wreak havoc on camera position]].
* This happens more than once in the ''VideoGame/{{Thief}}'' series.
** In ''VideoGame/ThiefTheDarkProject'':
** In "Lord Bafford's Manor", the two-story high atrium. It gives the archers clear, protected shooting, though.
** In "Down in the Bonehoard", the Halls of Echoing Repose are built in the shape of huge hexagonal light wells, the walls of which are tombs.
** In "Assassins", the atrium of Ramirez' mansion is the size of a ballroom.
** In "The Sword", the light well containing the sword itself. Arguably a JustifiedTrope, since the whole mission is a test to see if Garrett should be hired to steal the Eye. The area in which the Eye is located ismercury somewhat similar to the area around the sword -- a levitating object with enemies guarding it below, but which is accessible from above.
** The ''[[UpdatedRerelease Thief Gold]]'' version of "The Sword", the Brobdignag area (doesn't appear in the Dark Project version).
** In "The Mage Towers", each of the four elemental towers has a ballroom-size or better area on the first floor above ground level. This is particularly noticeable in the Water Tower (in which the space is largely flooded and almost empty) and the Air Tower (which has gigantic air shafts that act as elevators, in addition to the oversized area previously mentioned).
* Frankly, a building's importance in ''VideoGame/WorldOfWarcraft'' can be measured by how large its interior is. Of course, even the materials used are larger then life. [[http://picklocksbrain.blogspot.com/uploaded_images/zeppelin_ride_for_alliance-717183.jpg How were those goblins able to lift that screwdriver?]]
** Some of the halls in Utgarde Pinnacle, which are about 2 stories tall for no apparent reason, and Naxxramas, which has several unnecessarily huge rooms. While most instances are larger than the space they should be located is, Naxxramas deserves a special mention for completely breaking all semblance of suspicion of disbelief. In order to fit all the 4 wings inside it, it has to be about 10 times bigger on the inside than the outside.
*** The final room in the Spider Wing takes the cake: A massive cylinder several times the height of the exterior building with no exits beyond the hole in the wall you enter it through.
** Many parts of Icecrown Citadel fall into this category, too, with the Forge of Souls set in a huge cavern that seems to house only a sparse couple of catwalks. Icecrown has the excuse of being built on a ''giant glacier'' that the majority of which sits below sea level in a huge rift. Arthas built his entire metal citadel to cover the damn thing. The players won't even truly see a ''quarter'' of the citadel's full interior.
* ''VideoGame/SuperRobotWars'' occasionally will have indoor missions, with fortresses or space stations that have room enough for whole squads of HumongousMecha to all ''fly'' in. A particularly egregious example is in ''VideoGame/SuperRobotWarsDestiny'', where the final mission takes place inside, and the game lets you choose as your battleship for the mission the Battle 7 from ''Anime/{{Macross 7}}'': A [[TransformingMecha transforming]] CoolStarship that stands 1400 meters tall (about 200 meters short of a mile), and it ''still'' has room to either fly or walk.
* The browser-based MMO ''Travians'' allows players to buy and furnish houses of ever-increasing size ([[AllegedlyFreeGame sometimes at considerable real-money expense]]). Since the only items of furniture that have a practical effect are beds, Roman baths and seating, most of the available houses are impractically large.
* Bowser's Galaxy Generator in ''VideoGame/SuperMarioGalaxy2''. Okay, galaxies are massive places, but considering the entire final level/galaxy takes place in what's maybe about 1% of the castle space, it's fairly well under this trope. And this backdrop castle is big enough the planets in the level each have their own gravity and orbit.
* Ship and station interiors in ''VideoGame/StarTrekOnline'' are several times larger than what appeared on any of the shows. The developers claim it's necessary for proper camera control to work.
* Many tombs and dungeons in the ''Franchise/TombRaider'' series.
* The interiors of the Collector vessel in ''VideoGame/MassEffect2'' seem like they're a lot larger than necessary. Shepard even theorizes the reason for this is the Collectors intend to "collect" every human on Earth.
** The Collector Base seen at the end of the game makes the vessel look comparatively miniscule, and the final chamber is absolutely massive. [[spoiler: Justified: it's where they're making a new Reaper.]]
* In ''Franchise/DragonAge'', the ruins of ancient civilizations like the Tevinter Imperium and pre-Blight dwarves are enormous, with towering spires or soaring vaulted ceilings ([[http://dragonage.wikia.com/wiki/Fort_Drakon Fort Drakon]], a former Tevinter outpost, is easily 10 times taller than anything else in Denerim). Fereldan and Orzimmar architecture of places people currently live tends to be much smaller, to the point of claustrophobic. It does reinforce the theme of Thedas' past being much more magical and HighFantasy than the present.
** Most of the old Tevinter buildings in ''VideoGame/DragonAgeII'' are also quite massive.
* ''VideoGame/{{Touhou}}'': Strictly, this is an unnecessarily large ''exterior'', but the garden of Hakugyokurou in the Netherworld is well over 1000 kilometers long. Luckily, the gardener is capable of superhuman speed. The Scarlet Devil Mansion's library is also known to be quite large (and BiggerOnTheInside), but whether it actually qualifies as this trope is unclear.
* ''VideoGame/DeadSpace2'': Given that it is based on space station you would though building space would at a premium, not so for the Church Of [[ReligionOfEvil Unitology]], who have large richly decorated rooms that hardly anyone would ever see. It does show how much power the Church has to have a place of worship bigger than an entire street of houses.
* Tristram Cathedral was dark and claustrophobic in ''VideoGame/{{Diablo}}''. In ''VideoGame/DiabloIII'', it looks like one giant cavern, with the player running around on rooftops.
* Played for laughs in ''[[VideoGame/FancyPantsAdventures The Fancy Pants Adventure: World 3]]'', where the king's bathtub is ridiculously enormous (king-sized, of course), being tall as the entire stage you're in.
* Many locations in ''VideoGame/StarWarsTheOldRepublic'' are guilty of this trope.
* Most rooms in ''VideoGame/PN03''.
* In ''VideoGame/SaintsRowIV'', Zinyak's flagship has interior passages big enough for the Saints' own decently-sized spaceship to fly around in with room to spare.
* In ''Videogame/{{Warframe}}'', both Corpus and Grinner starships have absurdly large interior passageways, though part of that comes from them being at [[MileLongShip least a kilometer long]]. Even the smallest corridor in a Corpus vessel is large enough to drive a small truck through, and seemingly BottomlessPits are common. Gameplay wise, the hugeness is justified to prevent the third person camera from freaking out and to allow LeParkour.

* ''Webcomic/GunnerkriggCourt:''
** The dormitory buildings for Year 8 students are reasonably-sized -- but they are located inside another building, [[http://www.gunnerkrigg.com/archive_page.php?comicID=309 so much larger that the floor, ceiling, and walls are all shrouded in darkness]].
** The room Antimony moves into after [[spoiler: her father returns]] is huge enough that four panels are devoted to Kat growing from a tiny speck as she travels the length of the unadorned corridor-like room to the tiny portion at the end that's actually being used. Although it's speculated that there is a practical reason for this: [[spoiler: that her father chose it to psychologically isolate her and discourage visitors or her from leaving.]] Kat's first words on reaching her?
--> '''Kat:''' Why is this stupid room so big?!
* The [[http://www.irregularwebcomic.net/1455.html Hall of Dworin]] from ''Webcomic/IrregularWebcomic''
* ''Webcomic/DMOfTheRings'' : [[GonnaNeedMoreX I'm going to need]] [[http://www.shamusyoung.com/twentysidedtale/?p=712 a lot more graph paper ]]
* ''Webcomic/SchlockMercenary'' has a [[http://www.schlockmercenary.com/2013-04-07 story arc]] where the current employer of Tagon's Toughs is the Oafan ambassador, whose current space station is as large as a planet, is big enough to stuff the planet Mars, and has a docking area big enough to dock ''battleplates'', the largest spaceships the U.N. has. How many battleplates could dock inside? "''[[http://www.schlockmercenary.com/2013-04-21 All of them]]''."
* ''Webcomic/{{Goblins}}'' likes this trope very much. Huge interiors can be found in basically any dungeon.


* Valhalla, Odin's hall for fallen warriors, has 540 gates, each one big enough for 800 warriors to walk in shoulder to shoulder.

* Gothic cathedrals in general. Many cathedrals and indeed many old-world religious structures have this characteristic as the sponsors, architects and craftsmen, seeing their work as personal sacrifice or symbols of God's vast power, tended to go all-out. Some rulers also built these structures as a show of wealth, and would also be motivated to make them as big as possible.
** The Seville Cathedral; built as a monument to Seville's wealth (read: for no other purpose other than showing off), its central nave is somewhere around the 115 meters x 76 meters x ''42 meters tall!''
** St. Peter's Basilica in Rome has a dome that's 42 meters in diameter. The rest of the church is... larger. It is the largest Christian church in the world and it's said that if its roof were to be removed, the second-largest church could be lowered inside, and the roof put back in place. The main reason for its size was to surpass the Pantheon (see below).
* The [[UsefulNotes/AncientRome Roman Empire]] positively adored this trope. As the first hardcore users of the monumental arch, the dome, concrete and other innovations that allowed for construction of mega-structures, they loved to show off their power by building structures with massively spacious interiors. Buildings like the Baths of Caracalla, the Pantheon and Hagia Sophia were designed specifically to awe people with vast, open, interior spaces. The Gothic Cathedral architecture mentioned above was itself inspired by Roman architecture.
* Italian dictator UsefulNotes/BenitoMussolini had his visitors cross an excessively-large room to meet him as a psychological intimidation tactic ''a la'' [[Anime/NeonGenesisEvangelion Gendo's office]].
* Among the structures planned for Hitler's new German capital (a completely rebuilt Berlin to be named "World Capital Germania") included a dome many times larger than any ever built. How it would be built was never fully engineered. The central dome of the [[http://en.wikipedia.org/wiki/Volkshalle Volkshalle]] was theorized to produce acoustics that would either render any speech unintelligible or magnify a speaker's voice to deafening levels, and would have been large enough to produce its own weather systems and indoor rain as the breathing and perspiration of its occupants precipitated. Since Berlin was built on swampland, the whole building would have sunk and/or collapsed under its own weight, but Hitler, being Hitler, decided to ignore this fact.[[note]]Hitler's chief architect Albert Speer, as a test of the Berlin soil's ability to hold large structures, had a nearly 13,000 ton concrete cylinder built called the "Schwerbelastungskörper" (heavy load-bearing body) in 1942, to measure how far it would sink into the ground. If it sank less than 6cm, the ground would be suitable for the gigantic buildings Hitler wanted. By the time measurements were stopped in 1944, it had sunk 19cm. After the war, the Allies wanted to destroy the cylinder so the ground could be used for new buildings, but it was too big to destroy without use of explosives and that would've damaged the nearby railroad tracks, so the Schwerbelastungskörper remains to this day.[[/note]] Similarly, the new Reich Chancellery was built to almost comical dimensions, intended to impress visitors in the way parodied in ''Film/TheGreatDictator''. Also planned was a ridiculously huge triumphal arch, more than triple the size of the Arc de Triomphe in Paris...with dwarfing the French arch being the sole purpose for its size.
* The Leipzig Market Hall has two giant 68-meter diameter domes on top of an otherwise very basic, albeit large, hangar. Apparently they constituted a novel solution to the architectural problem of holding up such a large roof.
* Not to be outdone, Stalin planned the [[https://en.wikipedia.org/wiki/Palace_of_the_Soviets Palace of the Soviets]] to have a domed audience chamber of similar scale to the ''Volkshalle'', but the exterior structure was to be even larger, with the dome surmounted by a skyscraper as big as the Empire State Building, with that topped by a statue of Lenin as big as the Statue of Liberty. This project never got further than a huge hole in Moscow before defeating the ''Wehrmacht'' became a greater priority, and the project died with Stalin. Also like the ''Volkshalle'', such a structure was pretty much impossible to construct, especially on Stalin's chosen site, the bank of the Moskva River.
* {{LetsPlay/Chuggaaconroy}}'s closet is as big as the ones from numerous celebrities. Stephen Georg was utterly shocked when he saw it for the first time.
* On a smaller scale, [[http://www.mcmansionhell.com/post/150135343136/flower-mound-tx some of the critics]] of [=McMansions=] point out the penchant of their builders for this trope, and the impracticality of it.
* The Museum [[https://universum-bremen.de/ Universum Bremen]] has an oversized chair and table. They are upscaled to show adults how toddlers percieve regular furniture.
