Description

The Church of The Holy Trinity, built in the Gothic style, features stone-faced walls and slate roofs. It is oriented from southeast to northwest, with the chancel located at the southeast end. The structure includes a nave, a northwest tower, side aisles with roofs that have gables running perpendicular to the nave, transepts, and a southeast memorial chapel attached to the apsidal chancel.

The clerestorey windows consist of three trefoil-headed lights set in arcading. Each bay of the side aisles has a gable and a window with two lancet lights topped by a quatrefoil. The northwest nave window has four lights, and there is a northwest doorway with a porch that has a lean-to roof, featuring a central gabled window and flanking doors against the northwest nave wall. The northeast tower rises three stories and has tall paired lancet belfry openings along with a pierced arcaded parapet adorned with octagonal pinnacles. Each transept contains a tall window with three trefoil-headed lights, while the chancel has an apsidal end with five paired lancet lights.

To the southwest of the church are vestries and a hall, linked by a corridor wing that has paired lancet-headed lights on either side of the doorway with a gable. The hall wing, positioned at right angles, features a triple lancet window in the gable facing northwest, a gabled porch facing southwest, and a two-light window beneath a small gable.

The walls are faced with yellow brick, accented by lacing courses of black or vitreous brick, and ashlar mouldings around the windows and arches. The nave is notably lofty, with a timber-framed and boarded roof supported by principal rafters resting on ornately carved stone corbels. The nave arches are set on circular columns with decorative capitals, and the side aisles also have timber-framed and boarded roofs.

Inside, there is stained glass, including a window depicting Christ in Majesty in the northeast transept and additional stained glass in the southwest transept. The southeast chapel features a window with three lancet lights and an oil painting of a pieta in an Italian style. The chancel walls are faced with ashlar, and the sanctuary has a marble floor, with a reredos and panelling added in 1939.
