From the church information leaflet, written by the current Rector, the Revd John Eade:
Inside the church, the present chancel layout and general appearance date from extensive alterations made in 1863,
under the direction of Thomas Henry Wyatt -- who was then the consultant architect for churches in the Salisbury diocese.
(His cousin was James Wyatt, who made extensive alterations to Salisbury Cathedral in the late 18th century.)

The four pointed arches springing from round columns that separate the north aisle from the nave are the principal feature remaining from the original Norman church.

The south aisle is said by the 17th-century Wiltshire historian, John Aubrey, to have been added in the 16th century by the Prioress, Cicely Bodenham.
At the east end of the aisle there was originally a chantry chapel, separated from the aisle by a wall. by the early 19th century the chapel was being used as a schoolroom;
but in 1863 this wall was removed, and this part of the church became the vestry.

The east window is a memorial, given by the widow of Sidney, first Baron Herbert of Lea, who died in 1861.

The roofs of the nave and chancel are wagon-headed, and were originally painted blue.
