Barn in Shannon County MO. This is in a Mennonite community.
The one below one was taken in an Amish community near Seymour MO.
I wondered about the projections on top, and did a bit of research. They are called cupolas, put there for added ventilation.
Back when hay was stored in barn lofts, spontaneous combustion was a dire threat to farmers. The cupola helped prevent the buildup of heat in drying hay.
