I was just in southern chile and saw this round barn at a german heritage museum. (see the attached pics)
In the display they said that one reason for the round barn was so that horses could be used to thresh grain out of the rain. I knew that round enclosures keep animals from being caught in corners, but had never heard of threshing grain out of the weather. It rains A LOT in southern Chile.…
Thought you might enjoy that bit of info and the pics.
