Trevenson Church

Trevenson Church is a Grade II listed church built between 1806 and 1809 by the Basset family of Tehidy as a chapel of ease to the Church of St Illogan in Illogan. The church features uncoursed killas rubble with granite quoins and a composition slate roof, with a tower added later. It is designed in the Gothick style and includes a nave, a small chancel, and a west tower that is partly embraced by the nave.

The narrow three-stage tower has angle buttresses on the first stage only, with weathered bands on the upper stages that are slightly set back, topped by an embattled over-sailing parapet. The west doorway is 2-centred arched with a chamfered surround and hoodmould, above which is a square-headed window with three round-headed lights and a hoodmould. The second stage features a clock face and circular windows with diamond leaded glazing on the sides, all with hoodmoulds, as well as louvred 2-light belfry windows with hoodmoulds.

The tall rectangular nave has two large, widely spaced 2-centred arched 2-light windows on each side wall, all featuring Y-tacery and delicate intersecting tracery with trefoils and a quatrefoil in the heads, diamond lattice glazing below, and narrow margin panes, all made of cast iron. There is an outline of another window on the north side, which may have been either not built or removed. An apex cross adorns the east gable, and the short one-bay chancel has a stepped triple-lancet east window.

Inside, there is a plain west gallery supported by two cast-iron columns, above which is a plaster coat of arms. On the south wall, there is a large painting titled "The Dead Saviour, Virgin and Angels" by John Bryant Lane, commissioned by Lord de Dunstanville of Tehidy in 1808 as an altar piece.
