Nuffield is a village in the Chiltern Hills in the South Oxfordshire district of the county, 4 miles E of Wallingford and 6½ miles NW of Henley on Thames. The church is on the southern edge of the village and is built of unknapped flint with ashlar dressings. It consists of a 3-bay nave with a N aisle; the 2 E bays of which have an arcade and the W bay carries a low NW tower with a shingled upper storey. The 3-bay chancel was heavily restored by Benjamin Ferrey in 1845. The only feature recorded here is a large Romanesque font with an inscription.

Nuffield is not recorded in the Domesday survey because it belonged to the royal estate at Benson before and after the Conquest. The two main manors were Gangsdown, held by Ordgar who held it freely in 1066, and under Miles Crispin thereafter; and Huntercombe, separated from Benson in the 12thc and given by the king to William Percehay, whose daughter married Eustace de Huntercombe. In 1330 Huntercombe manor passed to Dorchester Abbey. According to the Victoria County History, the church, on the S boundary of Nuffield, may have belonged to the Bolbecs of Crowmarsh Gifford in the 12thc. In any case, Walter Bolbec gave the church to Goring Priory, certainly before 1181 and probably in the early 12thc. In 1362 the Trinitarian friars at Oxford obtained the advowson from Goring, and it has been suggested that this was the reason for a change of dedication from St Peter to Holy Trinity.

The inscription on the font has caused some disagreement. The word SACRI has been read as an abbreviation of SACRAMENTI in order to give the correct metre to the verse, but Field objects that this is unsatisfactory, as the verse should rhyme and that SACRI as written is would make perfect sense if another word had been omitted at the end. He suggests LAVACRI .

The effect on the translation would be to replace the word 'sacrament' with 'sacred bath', which the present author does not agree with.

The large size of the font suggests a date c.1100.
