Bradford-on-Avon Tithe Barn is one of the largest medieval barns in England, and architecturally one of the finest. It was built in the mid-14th century to serve Barton Grange, a manor farm which belonged to Shaftesbury Abbey in Dorset, the richest nunnery in medieval England. After the abbey was suppressed in 1539, the barn passed into private hands, and was part of a working farm until 1914.
