St Non's Church ( previously listed as Llanerchaeron Church)

St Non's Church, previously listed as Llanerchaeron Church, is a single chamber church featuring a west tower topped with a dome. The church is constructed of rubble, originally covered in stucco, and has a low plinth. It has a slate roof with overhanging eaves and a decorative iron finial on the eastern gable. Each side of the church has three pointed windows with stone voussoirs and timber cusped Y-tracery dating from 1895. The eastern window is similar but has three lights and intersecting tracery. There is a pointed priest's door on the south side, which features a boarded door and stone voussoirs.

The slightly projecting low west tower has a blank quatrefoil on each side and a pointed west door with paired boarded and studded doors, also with stone voussoirs. To the left of the west door is an inserted pointed window with a brick head. A plain stone dripmould runs at mid-height, originally continuous until the battlements were removed. Above this is a cruciform loop containing a crucifix. The tower has large pointed belfry openings with timber louvres and stone voussoirs, along with a stringcourse and a plain stepped stone cornice above. The short corner pinnacles have replaced taller ones, and the octagonal dome is metal-clad, a 1960 replacement of the original dome.

There are pointed doors on each side of the tower entry, along with a plaque recording the building date and a restoration in 1878. A pointed door leads to the nave, which features an 1895 arch-braced roof with kingposts and curved struts. The chancel and sanctuary are raised. On the west side, there are two early plaques: to the left of the door is a crudely carved relief of a lion with an incised trumpeting angel below, along with graffito dates of 1758 and 1775. To the right is a memorial to John Lewis, who died in 1738, with a Greek inscription below. There is also a simple pedimented plaque to J.W. Lewis, who died in 1855, created by T. Marsh of London.
