Interesting. I’d not heard of those before. Are they dateable?

Here in England, on the other side of the world, we have similar structures that have been dated back to the Bronze Age (3000 to 6000 years ago) These had a rock base, with mud/daub/wattle upper walls with thatch or turf roofs.

The similarity probably isn’t that surprising, people have needed shelter and use what’s available to make it. Even modern ruins from a few hundred years ago look pretty similar.

(One example below from Dartmoor, there’s thousands in this area)
