A tithe barn was a type of barn used in much of northern Europe in the Middle Ages for storing rents and tithes. Farmers were required to give one-tenth of their produce to the established church. Tithe barns were usually associated with the village church or rectory, and independent farmers took their tithes there. The village priests did not have to pay tithes—the purpose of the tithe being their support. Some operated their own farms anyway. The former church property has sometimes been converted to village greens.

A barn is an agricultural building usually on farms and used for various purposes. In North America, a barn refers to structures that house livestock, including cattle and horses, as well as equipment and fodder, and often grain. As a result, the term barn is often qualified e.g. tobacco barn, dairy barn, cow house, sheep barn, potato barn. In the British Isles, the term barn is restricted mainly to storage structures for unthreshed cereals and fodder, the terms byre or shippon being applied to cow shelters, whereas horses are kept in buildings known as stables. In mainland Europe, however, barns were often part of integrated structures known as byre-dwellings. In addition, barns may be used for equipment storage, as a covered workplace, and for activities such as threshing.
