A field barn is an outbuilding located in a field, some distance from farmer's residence or the main cluster of buildings that constitute a farmstead. Field barns were necessary when arable fields or valuable pastures were located some distance from a village or the residences of the agricultural workers who tended the fields. Rather than "commuting" back and forth to the field with livestock, tools, or harvests, the field barn allowed on-site storage, as well as providing shelter for herds during inclement weather or when pregnant cattle or sheep needed respite and a clean place to labor. Field barns were also used for the drying and curing of hay, which protected the nutritional content of the crop better than drying and curing in the field.
