Built of roughly coursed stone rubble with ashlar dressings,[2] the porch and the bell tower are the oldest parts of the church[3] with their remains of Norman arches dating to the 12th and 13th-centuries.
Between the 13th and 15th-centuries the church was enlarged and embellished so that it now comprises two aisles with two parallel roofs, one smaller than the other and decorated with Perpendicular-style pillars and arches.
At this time a singing gallery was added at the back of the church in order to accommodate a string band while the window frames with their fine tracery were also removed.
[2] Scott reversed the earlier "improvements" with the singing gallery being removed and eight new columns being reintroduced decorated with vines, fruit and faces (some grotesque) connected along the length of the church with Gothic-style arches.
Above the main door is a large painted panel depicting the Royal Coat of Arms of Queen Anne which was placed here sometime between 1707 and her death in 1714, as the insignia shown are those of the monarch after the Acts of Union of 1707.
The wall monuments and tablets are to Susanna Davie, (d.1694), with its oval medallion swathed with drapery, a scallop and skull to the base and amorini to each side.
