The earliest features of the building are the windows to the chancel which suggest a date of early C14 which is substantiated by documents.
In the C15 a major remodelling took place, evident in the nave and north aisle and the tower and north transept are likely also to date tothe C15.
The small south transept known as the Gidley Chapel by Bartholomew Gidley as a mortuary chapel for himself and his descendants, was added in the early C17.
A major restoration was undertaken in 1871-3 costing £6-7,000, by J F Gould which included amongst other carved stone and woodwork carved wooden bench ends by H Hems, the painting of the roof by J Thorne of Crediton and internal redecorating with sgraffiato plastering by Gould in collaboration with Radford.
