A large farm building used for storing farm products and sheltering livestock.
So if they are not large, are they not barns?
Roof sagging seems to be the first step.
This is the first one I came upon today that was red. When I was growing up, "barn" and "red" always went together.
My barnstorming today had a plan, that I would end here at the Marble barn. This round barn is a landmark in our town--and from the development nearby, it sure looks like soon the IN will be literally taken, as the next street over now has curbs and there is a real estate development farther down. (I hope it doesn't go the way of Kelly's barn. It has been preserved over time, so it has hope.)
At one time I was told the history of the Marble Ranch and the reason it was round. The reason has faded from my memory, but I believe it had something to do with feeding the cows. Maybe someone knows why this barn might have been built in this form.
What are barns like where you live?
