Trewellard Wesleyan Chapel

A nonconformist (Wesleyan) chapel, built in 1833 and refitted in the late 19th century. The front is built of granite ashlar, while the remainder of the chapel is granite rubble with granite dressings. It has a concrete tile roof with coped ends, and a triangular pediment over the front. The building has a rectangular, aisle-less plan with a gallery on all four sides. The side elevations are two stories high; the symmetrical front has two windows on each side, featuring round-arched openings. The windows contain late 19th-century horned sash windows with spoked fanlights, also present in the first-floor windows of the side elevations. A wide central doorway is topped with a good spoked fanlight and features a pair of single-panel doors.

The interior retains the original panelled and moulded gallery fronts on three sides, with canted corners and supported by slender Tuscan columns. A particularly fine feature is the moulded and carved plaster ceiling rose. A later, 19th-century gallery is located at the ritual east end, with turned balusters and panelled piers. The rostrum from the same period has a lectern projecting from a turned balustrade, standing on Tuscan columns with a round blind arch between. The pews, organ, and a glazed chancel screen, all from the late 19th century, are also present, the latter featuring Gothic detail. An attached vestry and other rooms contain some original features, including a moulded chimneypiece with corner blocks and roundels. The chapel is a good example of a galleried building within a mining village.
