Marston Montgomery is a small village in the SW of the county, in the Derbyshire Dales district, 6 miles S of Ashbourne and 13 miles W of Derby. The sandstone ashlar and rubble church is substantially 12thc throughout, and stands in the centre of the village. It consists of a nave with a W bellcote a N aisle and a S porch, and a chancel with a N vestry. It was restored in 1824 and again by H St Aubyn in 1877. Romanesque features described here are The S nave doorway, S chancel doorway, chancel arch and the font.

Marston Montgomery is not mentioned in the Domesday Survey, and may have been included in the manor of Cubley, held by Siward before the Conquest and by Ralph from Henry de Ferrers in 1086. The manor did include a priest and a church, although whether it was the one at Marston is uncertain. The church was a chapelry of Cubley and in the 17thc the same incumbent served both churches, although it kept its own registers.

The simple chancel arch and the capitals of the S nave doorway suggest a date at the beginning to the 12thc.
