Before the Norman conquest of England, Leofwine of Barton held the manor of Duns Tew along with those of Dunthrop, Little Tew and Westcott Barton. The Domesday Book of 1086 records four estates in the parish, of which the two largest belonged to Robert D'Oyly and Robert de Stafford. In addition, Gilbert de Magminot, Bishop of Lisieux held an estate of three hides and Odo, Bishop of Bayeux and half-brother of William I held an estate of one hide. The present manor house contains 17th-century remnants and a wing added in the 19th century, but the main part of the present house is 18th-century. The house has a 17th-century dovecote. Priory Court, a 19th-century house east of the church, used to be the vicarage.
