Parish Church of:
This parish, together with Cornelly, formerly formed part of Probus; an ancient record, dated 1727,mentions that this parish was made parochial 200 years to that date.
The church of St. Cohan is a small building of stone, in the Decorated style, consisting of chancel, nave of four bays, south aisle, south porch and a western tower with an upper stage of wood, containing 3 bells; the chancel retains a piscine and a niche inclosing a figure, said to have bee brought from the well-chapel of S. Coanus, about a quarter of a mile distant; there is a monument to the family of Blake, 1718-46, and one in the churchyard to Thomas Couch and Mary, his wife, 1622; on the cover of the chalice forming part of the church plate is inscribed the date 1576; there are 200 sittings. The register of baptisms dates from the year 1658; marriages, 1754; burials, 1682.
A mission church was erected in 1878, at Tresillian, at a cost of £300, and will seat 84 persons; it is now served by the vicar of Probus. In 1852 a font was discovered by the Rev. Frederic Webber, late incumbent, on a spot about quarter of a mile north from the parish church and supposed to have once been the site of an ancient baptistery
