Church Of St Keyne

The Church of St Keyne is a parish church largely dating to the 15th century, with origins in 1259 and significant restoration work undertaken in 1819 and 1860. Constructed of local rubble with granite and freestone dressings, it features dry Delabole slate roofs with coped gable ends and crested ridge tiles. Originally cruciform, the remaining north wall of the nave, chancel, and possible foundations of the north transept are visible, alongside extensions added in the early 15th century, including a south aisle, south porch, and a west tower. A later 15th-century organ transept was rebuilt, likely in 1860. The three-stage west tower has angle buttresses, string courses, an embattled parapet with crocketed pinnacles, a round-arched doorway, a 15th-century three-light traceried window above the doorway, and traceried louvred windows to the belfry. The tower windows are in a late 15th-century Perpendicular style. 15th-century windows in the north and south aisle feature Y tracery, some of which has been restored in the 19th century. The 15th-century south porch doorway has moulded responds and a 4-centred arch, with a similarly arched inner doorway. The church contains 19th-century windows to the transepts, west window of the aisle, east end of the aisle, and a five-light east window to the chancel, displaying interesting tracery.

The interior features plastered walls, a 15th-century tower arch, and a tall standard A-type arcade with 4-centred arches. Waggon roofs cover the nave, chancel, and aisle, while arch-braced roofs are in the transepts. Memorial windows with coloured glass include depictions to the Carlyon family in the east chancel, George and Jacobi Cornish in the north chancel, J R Cornish in the south chancel, and the Carlyon family in the west tower. Further memorial windows are dedicated to Tippett and Blamey in the choir aisle, Reverend Charles Burgess in the east, and William Mansell Tweedy in the west of the south transept. The church contains a letter written by Charles I and 19th-century fittings such as a granite font, pews, a pulpit, and a freestone reredos with a trefoil-headed colonnade of nine bays. Monuments include a late 18th-century wall monument to Edmund Powell in the north transept, a monument to John Richards Paul of Bosvigo from 1826-1907 in the south transept and Gothic-style limestone wall monument to William Mitchell from 1845, further marble monuments with urns by Isbell to George John (and family) from 1808 of Trehaverne and by King to George Nicholas John from 1797.
