Church Of St Nicholas

The Church of St Nicholas is a parish church dedicated to St Nicholas. It features a Norman font and a late 15th century west tower, while the nave, chancel, vestry, and south porch were rebuilt between 1878 and 1881 using some earlier materials. The church is constructed from snecked local stone and has slate roofs.

The layout includes a west tower, nave, chancel, south porch, and vestry. The west tower is a small, unbuttressed structure with two stages, topped with crocketted finials. It has a late 15th century west door arch made of granite with a basket arch, incised spandrels, and a hood mould with a 19th century door. There is a 16th century two-light west window with round-headed lights and incised spandrels, along with two-light belfry openings. The nave and chancel feature one, two, and three-light lancet windows, partially reusing late 13th century tracery in the chancel and the south wall of the nave. The vestry has a 19th century shouldered arch, and the gabled south porch displays two-centred inner and outer arches. A section of a pierced wheelhead cross is reset in the east wall of the porch.

Inside, the church has unplastered walls and 19th century roofs that incorporate reused carved bosses in the chancel. The rounded, chamfered granite tower arch rests on corbelled brackets. The furnishings, including the pulpit and brass lectern, are from the 19th century. A piscina and holy water stoup may have been reused from the earlier church. The Norman font features a round bowl decorated with a cable band, a round shaft, and a square base. The bells have been removed from the bell frame, with two now on the floor of the nave, dated to Samuel Holman in 1687 and featuring a marginal inscription. Notably, John Wesley preached at Tresmeer in 1745, 1748, 1750, and 1751.
