Wow, some amazing buildings. Thank you for the history lesson, Yamadude! Never seen comparable round buildings on farms in Britain - the internal detail of construction maybe shows why, must have taken a lot of labour and resources to build one of those?

I'm always interested in how words are used. The meaning of barn seems to have shifted and has become a general term for any large, uhm, shed on a farm. When I was little and use to play on farms - happy memories, just like Bob - barn meant a place for storing crops. An animal shed, specifically for cows, was a byre and usually had a hayloft above. Often with cats living there! The building set up for milking cows was a milking parlour. A big, often open-sided shed for hay was, surprisingly, a hay shed. Tractors were kept in the tractor shed.
There are some traditional very old barns in England, varying in size, of wooden construction but placed on mushroom-shaped stone stilts. The stilts were to keep rats out of a building filled with oats, barley, wheat. Not aware of any in the Borders so gonna have to surf the web to find a picture:

Also in England, there medieval tithe-barns, which are some of the finest surviving buildings from their time. This is Great Coxwell tithe barn, built about 1292 by the Cistercian abbey of Beaulieu to store grain:

In the 21st century, people put up a retail building on a farm or just anywhere rural with a large internal space, perhaps as a coffee shop or farm shop, and they always seem to call it a barn.
Every time I see one of your posts with a historically significant structure, I am reminded of just how young our country here is. The first American colonies weren’t established for another three hundred plus years after that Coxwell barn was built and it still looks like new! Amazing!
