Looks kind of like a barn, though I can't be sure.

we always feel badly when we see a classic in disrepair..

and had the smell of hay. Different in winter and summer. The ground level housed the cows in the winter. They were pastured in the summer.
Ground level was not as cold in winter due to the cows and manure. Smelled like cow poop but also from food they ate. Silage which was chopped corn, stalk and all, blown into the silo in fall and fed in the winter. Put chopped corn kernals mixed with oats on top of the silage. Cows loved it. They were also fed hay and bedding was straw so those smells were there too. Cows breathing in cold temps made a mist. Hauled manure and spread on fields during the winter. We wintered about 250 animals and had about 200 calves each year. Sold breeding stock across the east coast and some to Texas. Herefords.
A couple barns remain but are not used.
