Morwenstow church is dedicated to St Morwenna and St John the Baptist. It was appropriated by the Bishop of Exeter to St John's Hospital at Bridgewater before 1291. In a document dated 1296, the church was referred to as an 'old and well-known structure'. Although this is a Norman church, it must have replaced an earlier Saxon structure. The chancel is separated from the nave by a richly-carved screen erected in 1575 by the Kempthorne family. It has a fine Norman doorway.
The arcades consist of seven arches, some of which are semi-circular, and others pointed. They are supported on piers and pillars, one of which bears the date 1475. The tower is of two stages and is finished with pinnacles; it had four bells.
There is an interesting, but defaced, polychrome wall-painting on the north wall of the chancel, which is thought to represent St Morwenna. It shows a gaunt female clasping to her breast, with her left hand, a scroll or volume; the right arm is raised in blessing over a kneeling monk.

I couldn't find the wall painting mentioned in the text above, but I do remember seeing it when we visited the church eight years ago.

The beautifully carved ends of these benches are from the late 16th century
