Depends on how metaphorical and/or political you want to get. Arguably books could be considered warning waystones, but that's a stretch in this context. Physical monuments though, we have loads, lots of war memorials are/were intended as warning about the cost of war. Auschwitz-Birkenau being left as as it is could be considered another. If you want to get really close to similar intentions there are the long term nuclear waste warnings: https://en.wikipedia.org/wiki/Long-term_nuclear_waste_warnin... A bit more esoteric (and less warningy) and you get the signals we send in to space intentionally as a time-capsule/marker for potential alien contact. |
