In early times St Eval lay within the episcopal fief and peculiar deanery of Pawton. In 1297 the benefice was appropriated to the Dean and Chapter of Exeter; in 1312 the Dean and Chapter were in dispute with the vicar about the repair of the chancel. This was settled in 1322 by the vicar lengthening the chancel by six feet and rebuilding its walls. The aisle and tower were added before 1662 and in 1725 collections were made throughout the diocese for funds to rebuild the tower. The merchants of Bristol acknowledged the usefulness of the church tower as a sea mark and provided the funds for this in 1727. The oldest part of the church is Norman but the north transept has been rebuilt. The south aisle is Perpendicular; the arcade has six arches but only four belong to the nave and the fifth arch is low but the sixth high again. Features of interest are the plain Norman font, the base of the rood screen, the octagonal pulpit dated 1688, and a good set of bench ends, reused in the restoration of 1889. The restoration was the work of J. D. Sedding. The stained glass (1989) commemorates the RAF station. The churchyard contains the war graves of 23 Commonwealth air force personnel of World War II.
