Church of the Holy Trinity (including Churchyard Monument & Boundry Walls)

The Church of the Holy Trinity is a plain 'Commissioners Gothic' building constructed from blue lias stone. It features a broad slate-roofed nave, chancel, south porch, and a narrow castellated west tower. In 1920, the church was altered externally by replacing the long Y-traceried lancets with flat-headed ashlar Perpendicular-style two-light windows, as well as a three-light segmental-pointed east window. The south side of the nave has four windows and a large circa 1840 porch to the left, which has a shallow gabled roof with an unmoulded pointed arch and a chamfered pointed inner doorway with double panelled doors. The north side is similar, featuring a chamfered pointed doorway to the right. The chancel has one window on each side.

The tower is plain, with a corbelled castellated parapet and plain louvred bell-openings. In 1920, ashlar tracery was added to the bell-openings and the ground floor west window. The tower appears to have been widened with stepped angle buttresses leading up to the bell-stage, which has raised angle piers and paired segmental arches under the corbelled parapet. The plain castellation was altered to include stepped corners.

The churchyard contains numerous slate headstones and three linked iron-railed tomb enclosures close to the south wall. There is a rubble stone wall along Church Street, featuring wrought iron gates and rendered piers.

Inside, the church underwent significant transformation in 1920. The original broad aisleless nave, which had a hammerbeam-type roof with five bays, was given passage aisles by adding square stone piers that extend to the undersides of the hammerbeams. The original panelled west gallery rests on quatrefoil columns. A fine Art Nouveau stem font with a beaten copper cover is present. The chancel features a boarded wagon roof and much finely carved woodwork from around 1920. The east window contains stained glass from circa 1924 by Horace Wilkinson, along with 20th-century glass in five other windows. There is a fragment of high-quality glass from around 1860 in the tower, suggesting that some of the tracery may have been reused. Additionally, there are two 19th-century hatchments belonging to the Halls of Cilgwyn, which were removed from Paddington Parish Church.
