I just saw the film *Dora and the Lost City of Gold*, in which there is a somewhat meta running commentary over whether so-called "jungle puzzles", intellectual challenges typically requiring explorers to push the right buttons, pull the right levers, step on the right tiles, make the correct offering to an idol, etc., and that stereotypically guard large caches of treasure in treasure hunting films, actually exist.

Did ancient peoples ever actually guard their treasure behind intellectual puzzles? To be clear, it seems to have been *extremely* common for treasure to be guarded by *security through obscurity* scenarios, with [passages hidden behind fake walls](https://www.nationalgeographic.com/news/2018/02/king-tut-tomb-hidden-chamber-scan-egypt/), stuff buried in the middle of nowhere, and [decoy artifacts and rooms](https://en.wikipedia.org/wiki/Southern_South_Saqqara_pyramid), but I'm having trouble finding any instances of actual *puzzles* of the kind that appear in *Indiana Jones* films and *Dungeons & Dragons* adventures, where the original designers seem to have *intended* that the puzzle be *solved* at some future time by persons deemed worthy enough *by possession of the correct skills or knowledge*.
