A tithe barn was a type of barn used in much of northern Europe in the Middle Ages for storing the tithes - a tenth of the farm's produce which had to be given to the church. Tithe barns would usually have been barns often associated with the village church or rectory, to which independent farmers took their tithes. This barn sits in Lacock Village which is entirely owned by the National Trust. No building in the village is more recent than the 18 th century and many are two or three hundred years older.
