The earliest building must have been of the 12th century, as there is evidence of 13th century additions.
The transept piers do not bond into the east wall of the nave, which, with its 4 feet (1.2 m) thick wall, probably formed part of the original church.
The eastern arches of the aisles spring from plain-splayed imposts, and the starting pier of the south aisle does not bond into the west wall.

The 13th century builders practically remodelled the whole structure, leaving it much as it is today—a nave of three bays, a fourth being formed by the transept arches, north and south aisles, a long chancel, north and south transepts and a south porch supporting a wooden tower containing six bells.
The massive piers at the entrance to the transepts suggest a central tower.
Both transepts are singularly deep and must have been original features, though the south one has been lengthened 10 feet (3.0 m), probably in the 16th century when the east window was inserted.
The aisles must have been undertaken later in the century, as they are not in alignment with the transept piers.
They both end in pointed arches, that to the north being splayed inwards for some ritual purpose, while the south one was rebuilt when the way to the rood-loft was cut through in the 15th century.
The south wall of the nave is lighted by 14th century windows with cusped heads, and has been raised to admit of their insertion.
The north wall is pierced by two windows and a door of the 13th century, the westernmost window having been converted into a single round-headed light in the 17th century.

The entrance to the roof-loft still remains, with its steps on the aisle side.
It has a semicircular head, from which springs the cross arch of the aisle with its two rings of voussoirs.

In the south wall is a priest's door.
For some structural reason, its east and south walls have been rebuilt in the 16th century, and it is probable that at this time, the south transept was lengthened 10 feet (3.0 m) and the porch widened eastward to form the sub-structure of a wooden tower containing the three bells mentioned in the inventory of 1553.
The west wall of the nave appears to be all of one date—c.
1200— and is pierced with three original windows, a small narrow lancet in each aisle, a circular window with simple cusped filling in the centre of the gable.
The crown of the west entrance has been lowered to admit of the insertion of a large 'churchwarden' window and the external jambs have been replaced with plain cut stone.

It is probable that the Dillingtons were responsible for the churchwarden creations in the north transept, and the west wall, and the final remodelling of the tower.
There are two small chapels succeeding the two transepts.
Over the gable of the south transeptal chapel, a "singular SAINTS or SANCTE BELL turret" has been erected (the bell was first struck when the image of the Saint was deified).
In the porch, there are inscriptions in Latin on two tablets that record the generous contribution made by Richard Gard to establishing a grammar school which was founded by Richard Andrews, in 1595.

The oak pulpit with its quaint sounding-board and canopy, as also the carved 'Pelican' lectern said to have been brought from Frome, belong to the Dillington period.
There are memorials (eight inscriptions) in the north transept to the Dillington family, 1674 to 1749, wall tablets to Lieutenant General Maurice Bockland (Member of Parliament from Yarmouth; d. 1765), W. Bowles (d. 1748), an author, and William Thatcher, 1776.
Over the south door is a panel with the royal arms of William III, dated 1700.

Chancel
The chancel, unusually long for its width, is lighted on the north by the three blunt lancets already referred to, on the east and south by three-light 16th century windows.
The original north wall of the chancel still remains with its blunt-lancet, ungrooved window openings.
Over the chancel arch is a wide splayed lancet window or opening of early 13th century detail.
The transept and chancel arches are very massive in appearance, with pointed heads and triple
