I remember reading a very interesting paper on how can we make nuclear waste dumps marked as unsafe for 1000s of years. It employed things like surrounding it with sharp, outward pointing dangerous objects, building a maze-like concrete structure around its general area and trying to create universally understandable pictograms to say “stay away”, even for a possible post-nuclear-catastrophe society.
Unfortunately I couldn’t find that paper again, but it was really interesting read and you might also find it interesting. Another similar topic that comes to mind is the https://en.m.wikipedia.org/wiki/Voyager_Golden_Record

This actually sounds like the perfectly wrong choice - it reminds me of various movies/TV where such traps are used around temples or tombs to keep treasure and sacred artifacts safe, making them prize targets for graverobbers or archeologists.
See also various ancient tombs (Egypt being primarily on my mind).
Wow, thank you very much for this! At times I even contemplated whether I just dreamt about this article, but I wouldn’t be that creative to imagine something like that :D
