St Catherine's Church

St Catherine's Church is a small, simple single-cell chapel built of rubble, featuring a medium pitched slate roof. The south side has three large arched leaded windows with simple tripartite wooden tracery and geometric tracery heads; the right window has a blocked entrance beneath it. The east wall has a similar window with two quatrefoils above three cusped lancets. At the west gable, there is a plain pedimented rubble bell-cote with an arched opening.

The church has a simple single-storey gabled porch with kneelered slate-coped parapets and a stone cross at the apex. The porch features an arched entrance with a stone seat and two boarded doors, one leading to the nave and the other, off to the north, providing access to an internal gallery. This gallery is reached via an added gabled stair projection that is slightly set back from and adjoins the porch to the north. There is a slit window on the ground floor with an arched leaded lancet above. Above the porch on the west wall, there is a plain leaded oculus.

To the north wall, there is a gabled late 19th-century vestry addition with a depressed arched window containing a two-light wooden mullion with shaped, arched lights. Adjacent to this, set back slightly, is a wider gabled projection made of snecked rubble, which is an early 20th-century boiler house with a flat, buttress-like chimney against the north wall of the chapel.

Inside, the church features a simple four-bay queen strut roof and a plain tiled floor. The nave and chancel are continuous, with plain early 20th-century pews and a simple wooden west gallery. There are 20th-century biblical texts painted in panels beneath the wall plate. The chancel has earlier 18th-century oak turned altar rails and an arched panelled dado, along with a tripartite wooden retable in a simple Gothic style. The square panelled pulpit and figurative stained glass in the east window commemorate Thomas Taylor of Penmaenucha and Arthog, who died in 1876. There are also early 20th-century wall tablets.
