The batcave, in any version of Batman, is large. Plus there's the batmobile, which required special construction, plus the batcomputer and numerous other batwidgets.

How did a good sized batcave get built without the land above it being torn up and without requiring a huge construction crew?

And, after the cave was built, how was the batmobile built in secret, without someone involved in it being able to make the connection between the car they built and the one that shows up in the news when Batman is first seen? (While he's in Gotham, a masked vigilante is news that would end up nation wide.) There would also be the need for secrecy so vilains can't find out how it is built and what the specs are.

And then there's the continual supply of batwidgets. Just as with the batmobile, there's the need for these items and how they work to be kept secret.

It'd take several factories to produce all that Batman uses and major construction for any batcave I've seen (which is in movies and on TV).

How is all this done in secret? (Or is there a trail of bodies?)

    In Batman Begins, the Batmobile was already built but was just outfitted by Wayne Industries' R&D team. – OghmaOsiris Jan 27 '12 at 2:02

    simple - the contractors were killed afterward – A.D Jun 11 '12 at 18:52

Building the Batcave (or refitting natural one extensively) in secret is no big deal - it's not like it's advertised that it will be the Batcave, AND almost nobody knows about batcave's existence afterwards.

As for Batmobile, depends on which reboot. As Oghma said in a comment, in the latest movies reboot (Nolan's), the Batmobile is an already-developed but never sold (due to cost) advanced prototype developed by Wayne Industries.

In the early versions, I believe the implication is that batmobile is modified by Batman himself, probably with Alfred's help - remember that in those earlier times, men were men and could rebuild a car engine or add extra features to the car (moreover, the very first Batman's car was a stock convertible with no extra features).

The rest of BatGadgets are also either:

  • Developed by Wayne Enterprises

  • Designed by Lucius Fox (CEO of Wayne E.), or in other reboots, Alfred.

Most of batgadgets aren't really fully identifyable as batgadgets until they are styled, so they can be produced by any contractor - just as workers at FoxConn have no idea that components X Y and Z they are making are actually designed for the new iPhone. Again, Nolan reboot makes references to Wayne Enterprises making super-large buys of components to make some few batgadgets, for purposes of hiding in plain sight.

  • Batman special built all of the Batmobiles until some time in the 90s when Harold Allnut started living in the Batcave and and BTAS popularized the idea that Lucious Fox developed it (with his son if I remember right). The same is true of all the batgadgets. It's only due to BTAS and Batman movies that Batman has been dumbed down with regards to his ability to develop and build his own stuff. – Durakken Jul 5 '16 at 12:42
  • "moreover, the very first Batman's car was a stock convertible with no extra features" Well, except for the big bat face on the front, or was this an optional extra? – jim Jul 12 at 15:03

    @jim Are you referring to the illustration on that Wikipedia page of a later 1941 version of the Batmobile, which is different from the red one the text mentions from 1939? – Admiral Jota Jul 12 at 16:00

The Batmobile in the Batman Animated series was build by an expert who used to work at Wayne Enterprises. This is the episode in which the batmobile is destroyed and needs to be replaced with a new one. I believe it is one of the first episodes of Batman and Robin the animated series which is season 3. So there are some different variations on the heritage of all the different kind of technology that Batman uses.


The cave itself is a natural cavern beneath Wayne Manor; all you really need to do is run some power lines and some ventilation (or install your own atomic pile). Although, given that there are bats and other critters living in it (along with a giant waterfall right outside the entrance, depending on the version), you'd probably want to build some enclosed spaces within the cave for your more delicate electronics, but it's not like that requires a lot of contractors.

As for the equipment, you have several options:

  • You can create a bunch of shell corporations to order parts from different vendors and integrate them yourself (such as the radio transceivers in the cowl from "Batman Begins");

  • You can take advantage of your multi-billion-dollar corporation's underutilized R&D department and hope the guy running it doesn't ask any questions, and then do the Bat-specific customization yourself (the body armor and the Tumbler aka the Batmobile, also from "Batman Begins");

  • You can do it the old-fashioned way and build it yourself. After all, you're rich, it's not like you have to punch a clock every day.

    Actually, bats and most creatures are not a problem in caves after the first 50 feet or so from the entrance. Of course, there are exceptions, such as with streams running through caves, or some very large caves, but in spelunking, if I recall, there's no problem after you get back from the entrance. – Tango Jan 28 '13 at 3:12

I believe in the comics, the Batcave was mostly not built, but was a pre-existing cave underneath Wayne Manor. See http://en.wikipedia.org/wiki/Batcave


One Batman novel put forward the idea that Wayne, through a series of shell corporations, hired a crew of experienced foreign workers and paid them an extravagant amount in advance, arranged to fly them secretly to Gotham while keeping them ignorant of where they were going, set them up to live comfortably in the cave while they fitted it out aside from the Bat-specific things, then when they were done arranged to fly them back home secretly with another extravagant payment. The only person they dealt with directly in Gotham was Alfred (in disguise).

So while they knew they were building some sort of top secret facility, they never knew where, or for who, and were compensated handsomely for doing the work and keeping their mouths shut.

    Does this novel have a name, author, and publication date? – T.J.L. Jul 12 at 16:33
  • Of course it does. I just can't remember what the title was. I'd bought it perhaps 25 years ago. Original story, not an adaptation of the comics, it featured an assassin hunting down Batman who figured out he was Bruce Wayne (after killing the other Gotham billionaire he's narrowed down the list to; he'd deduced Batman had to be one of them and decided just to kill them both to be sure) and it ended with a confrontation in the Batcave where the man fell to his death. – Keith Morrison Jul 12 at 21:49
  • My point was that without proper references, this isn't much of an answer. – T.J.L. Jul 12 at 22:37

Going back to the original source (the comics) Ra'as Al Ghul was able to infiltrate and ambush Batman in the Batcave. He extrapolated that it was rather easy for him to follow the money trail to this most secret of locations. IMO I think much of the Batcave work was done by Superman, a good friend and ally crime fighter. He built his Fortress of Solitude himself.

Some comics say that the cave was actually developed by Bruce's ancestors who were part of the underground railroad of the 1800's. It was used to smuggle slaves to freedom. Although if we consider the commonly held belief that Gotham City represents one of the great cities of the Northeast, Boston perhaps, one has to wonder why the slaves needed a place to hide when they most likely were on free soil.

But beyond that, when you look at the layout with all its concrete work, massive old fashioned computers, and etc. it must have taken at least a few people to put that together.

I'm reminded of the Great Pyramids of Egypt and their secret passageways to chambers filled with gold and jewels. I imagine Batman must have done something similar. First highly skilled workers were brought in under cover of darkness and blindfolds and housed and fed while the meticulous labor was carried out. Then when all the extensive labor had been completed and everything was up and running, Batman killed them off to safeguard his secrets.

It seems kind of obvious when you think it through. I mean the guy is just not right in the head. Extracting free labor from runaway slaves who didn't know where they were seems to have been a Wayne family tradition. So now you know where they got their money too.

    Batman isn't as moralistic as Superman, but it seems like quite a leap from him being willing to kill to think he'd choose the mass killing of laborers who haven't committed any crimes rather than a different method of secret construction. – Bellatrix Aug 25 '17 at 1:32
  • Why do you assume that the workers weren't criminals? I'm still going with the descendants of runaway slaves who never knew the freedom they rightfully deserved. Rich people like to do that sort of thing. But setting that aside maybe Batman used criminals for slave labor before killing them. Bruce doesn't have time to be pouring concrete himself. He's got crazed lunatics to round up so they can escape every few months. – MuddyWolf Aug 25 '17 at 3:21

    I would agree with @Bellatrix about his willingness to kill in that way. Even if the builders were criminals, what he's doing would be premeditated murder. It's hard to imagine him going that far. Blindfolding? Yes. Even having things done in parts and later assembled so nobody knows what the totality is, but planning to murder a group of people? No. – Tango Sep 3 '17 at 17:20

Batman does not kill, the cave is mostly natural. Batman clearly has a dedicated group of people who know who he is. Like seriously if you think about it his identity isn't all that secret. He is rich people, rich, he is bound to have friends and know how to get things done secretly.

    This is a partial answer in that you state "the cave is mostly natural", could you edit in a reference that, that is indeed the case? However, it doesn't address the point about the batmobile/batwidgets and that the batcave would have needed work doing to it. If you could expand on this a bit more to explain how he does that in secret (which you sort of hint at) and add sources/evidence this could be a nice answer. – TheLethalCarrot Jul 12 at 13:25

    Also the "a dedicated group of people who know who he is" part could use some supporting evidence. – DavidW Jul 12 at 13:31
