Description from record TQ 96 NW 1:
[TQ 90886540] Holy Trinity Church (NAT) (1) Holy Trinity Church, Milton Regis, is mainly 14th c. but there are traces of Roman material and early herring-bone masonry which are almost certainly pre-Norman. [See TQ 96 NW 8, for probable source of Roman material]. (2) In normal use. (3) TQ 96 NW 7/59 Parish Church of the Holy Trinity 10 9 51 Grade B. C14. Restored by W L Grant in 1889. Flint-faced with stone quoins, window dressings and buttresses. Nave and chancel with south aisle to both and crenellated West tower with flint and stone buttresses. South porch. C15 windows. C14 roof. Piscina and sedilia. C14 octagonal font. (4) Holy Trinity Church, Milton Regis is of flint and ragstone, attractively textured outside and it incorporates some Anglo-Saxon herring-bone masonry. The tower probably dates from c.1325, the south arcard has typical 14th century form and the road is early 14th century. (5) TQ 909654. Holy Trinity, Milton Regis. There is little now surviving in the fabric of the church to fix any part of it with certainly as a survival from before the Conquest, but the north walls of the nave and chancel are clearly of some antiquity. They are of big brown uncut flints and occasional Roman tiles, laid in rather random fashion, but with some herringbone courses. The whole of an originally aisleless nave and chancel remains, with a wide aisle added later on the south, a vestry on the north of the chancel, and a very large west tower about 25 feet internally (6,7).
