In the late Norman period South Newington's church had a nave of two bays, plus a north aisle and a chancel.

Features that survive form this period include a pair of Norman arches between the nave and north aisle.

[8] Another author commented: "The north aisle paintings at South Newington are indeed outstanding for their draughtsmanship, wide range and skilful blending of colours, and also for the medium, which is oil; nothing in this part of the country can compare with them for excellence.

"[9]The paintings in the north aisle include a damaged but very fine depiction of the murder of St Thomas Becket.

[10] The east end of the north aisle forms a Lady Chapel whose wall paintings include an Annunciation[11] and an exquisite Virgin and Child.

Late in the 15th or early in the 16th century, after the clerestory was built, a Passion Cycle was painted in the nave above the arches to the north aisle.

St Peter ad Vincula is now part of a single Church of England benefice with the parishes of Bloxham and Milcombe.
