Farm building traditionally used for the storage and processing of cereal crops and hay. On older farmsteads, the barn is usually the largest building. It is often characterized by ventilation openings rather than windows and has at least one set of big double doors for access. Before mechanization, wheat was threshed by hand on a specially prepared floor inside these doors.
Tithe barns were used in feudal England to store the produce paid as a tax to the parish priest by the local occupants of the land. In the Middle Ages, monasteries often controlled the collection of tithes over a wide area and, as a result, constructed some enormous tithe barns.
