Dwarves.

Dwarves did it.

Reading this triggered my anxiety ....

Pure nightmare fuel here - though I couldn't stop reading.

This is interesting - have a look at "teach allais" in ancient Ireland - literally means "houses of sweat" which were used for ritual purposes similarly to native american sweat lodges. It's likely this practice was common among Celtic peoples right across Europe and into Anatolia.

My bet is these were for something like that maybe.

The past really was a different country

Hiding places! Old school panic rooms. There was a raid and you needed to hide your kids. You wanted the space to be impractically small so that an armored dude can’t follow you in, and his scary weapons are rendered useless.

This is one theory! But if someone hostile sees you go down there, surely they’re just blocking the entrance for a few weeks? :((

Laura Moore's avatar

Yes if you’re important and have resources, but in that case you probably have the protection of a castle or other fortification. These tunnels would be for ordinary people. The cost of waiting them out in terms of logistics and exposure yourself isn’t worth the upside.

Ah, yeah, to avoid the crimes of opportunity (to create a euphemism) by invading armies or gangs of bandits.

Magyar raiders don't wait around for weeks when there's easier loot elsewhere. On the other hand they stopped raiding after around 960AD, and the Vikings rarely made it that far south. A mystery.

You can hide children down there. The parents die, sure, but the kids can still live (and with a little food squirreled away). The parents maintain "we have no kids", and who's going to sit there for days to ... get small children? They're not even of much use as slaves.

But why would they be in Churches instead of homes?

J Rainstar's avatar

because the church might be a common gathering place

One word: purgatory

weird medieval guys's avatar

what’s crazy is, these tunnels basically predate the Christian idea of purgatory

Julian Usslar's avatar

I thought that appeared in Ireland in the 7th century with St Fursey and retroactively assigned to St Patrick

I hate to take the mystery out of the erdstall, but maybe they are simply drainage - possibly even sewage drainage. Maybe there were outhouses at the tops of the erdstall where it emerges to the surface.

Zanni's avatar

I could see that in clay, but in granite? That's a lot to dig through... and sewage is a finite quantity... it would overflow eventually.

Thanks for tickling my historical mystery bone! These will be an excellent addition to my fantasy novel, with some magically mundane or fantastically ridiculous purpose. I really enjoy weaving in real-world oddities like this. The Erdstall will join the Aztec Death Whistle and the Korean Bongsu as part of the world of Venn in The Unexpected Vanguard!

That's what I was thinking. People have weird hobbies sometimes.

lexi's avatar

i weirdly find these kind of vibey i'd hang in one

weird medieval guys's avatar

actually in one of the articles i read about this one of the german farmers who has one on his land says he just crawls in for fun and chills out sometimes!

lexi's avatar

HELL yeah put a couple rugs and pillows down there

Autism is one hell of a drug. :- )

Absolutely fascinating! What an intriguing mystery.

The first thing that came to mind is that these may have just been either sewers/drains or tunnels to transport water.

They had a lot of that in Medieval Europe, especially in Germany it seems.

Drinking water or water for bathing or maybe to get rid of water.

weird medieval guys's avatar

for sure a possibility. but even then, there is a mystery: why dig them in such specific configurations? Most wells, peoole threw things down them. so why did no one throw anything down these ones?

The Fake History Hunter's avatar

Yes, the stone type also makes little sense, it absorbs water, however, weve also seen tunnels built for pipes, like sewers, so you'd have a stone tunnel and in that tunnel there were wooden, clay or lead waterpipes, the tunnel would only be for emergency maintenance.

But that also wouldn't make much sense here.

Still, I'm leaning towards a rational logical function.

Kadmon's avatar

Is it possible that digging such tunnels was some kind of penance?

The Blind Man Sees's avatar

Heard a theory that they were dug by some long extinct megafauna and that makes the most sense to me.

Lucy's avatar

Any animal origin would surely have left food scraps or bones or scat

O. Orca's avatar

I like this... primeval vibes

The Blind Man Sees's avatar

They have found similarly sized tunnels in the Amazon that were traced back to giant sloths and armadillos. The tunnels in the Amazon are six feet tall and often dug through solid rock. I am no paleontologist, but if the tunnels are old enough we wouldn't expect to find much surviving on the inside other than rock and dirt as we need specific conditions for bones, food, and scat to survive for thousands of years without decomposition.

Since many of them seem to be in Bavaria and Austria, it makes me think they were for storage or as temporary shelter. For example, the Felsengänge (stone passages) in Nuremberg started out as individual landowners digging ever deeper cellars to store beer. Multiple people then began connecting theirs. It is strange that so many are discovered almost completely empty, though.
