As people spent time in them, the oxygen would run out and be replaced with carbon dioxide, which is heavier than air and would sink to the bottom. With no exits and no airflow, wouldn't this become a straightforward deathtrap at some point? Or were there ways to force clean air to the bottom, somehow forcing out the CO2?

Seems to me that a secure hiding place that only works for up to N hours then becomes a death trap is a really bad concept

Based on just this article, it seems far most likely to me that it was a place to hide during an attack. > And while three brave explorers in the 21st century once spent 48 hours in an erdstall, crawling to new sections whenever oxygen became scarce, it seems unlikely that they would have been constructed as hiding places, even temporary ones. Though they could have provided refuge for a small family, why would they…

Indeed: that would help reconcile the presumed secrecy with the fact that, also per the article, there are upwards of 2000 of these tunnel-structures that fall into this category. All across Central Europe. Aggressor knows THAT there's likely a safe-tunnel, but doesn't know exactly WHERE the safe-tunnel is, and whether it's worth taking the time to find...

For that matter—A place to stash the kids from the census-taker and the harvest from the tax man? Tuck them away, just for that day, once every so often, and pull them out afterward?

Or knowledge privileged to some specific order, whose representatives are geographically widespread but sparse within a given community?

Tunnels through which dogs could carry packages or messages no matter what the weather was like and without fear of getting lost or interfered with on the way? The chambers at the ends could have been where the dogs slept and were fed.

And then returned the message back to the single entrance?

No way I’d hide in a hole without another exit. And if I went to the trouble to dig a hidey- hole I’d prepare it with a jug of water and a snack.

Earlier quoted context omitted.

There's zero reason to expect remnants of food, as well. It was not shelf(tunnel)-stable.

There would still be signs. The food rots - but it would leave traces.

Only if the tube was used for long enough to need food.

If you are hiding your family from almost certain death, 24 hours with no food or water in a cool dark cave is a possibility.

If the alternative was being hacked to death, I venture to guess you probably would.

If you only need it for less than N hours, though, it might be a really good concept
