[2] The church is mentioned in Daphne du Maurier's Jamaica Inn; it is the church in which the evil vicar of Altarnun Francis Davey depicts himself in a painting as a wolf while the members of his congregation have the heads of sheep.

Most of the church dates from the later part of the 15th century, at which time the north and south aisles were added.

It is notable for the fine Norman font and the amount of old woodwork, including the screen, bench-ends and communion rails which date to 1684.

The screen is one of the finest 15th century examples in Cornwall; it has three gates and the cornice of vines and tracery and vaulting are finely carved.

[6] Also, one of the damaged pew ends was repaired to its former glory by the late local master joiner Douglas Edwards in the 1980s.
