The Domesday Book records that by 1086 Gilbert de Magminot, Bishop of Lisieux held Westcott Manor.It remained in his family until early in the 12th century when Gilbert's grand-niece Alice Maminot was married to Ralph de Keynes.[2] There is archaeological evidence that by at least the 11th century there was an Anglo-Saxon stone church at Westcott Barton, which was originally dedicated to St Edmund the Martyr.[5] In the 14th and 15th centuries the chancel and north wall of the nave were rebuilt, the west tower and battlemented south porch were built[2] and the wooden rood screen was installed, all in Perpendicular Gothic style.[4] In the churchyard just south of the church are a 15th-century tomb chest that has a quatrefoil at either end, and the base and steps of a late medieval stone cross.In 1538, in the Dissolution of the Monasteries, the Abbey surrendered all its property to the Crown, which in 1557 sold the advowson of Westcott Barton to a secular buyer.Earthworks indicating the sites of buildings survive to the west, south and east of the churchyard.
