Church of St Rhian

The Church of St Rhian is a Grade II* listed building constructed from random rubble stone, featuring low-pitched slate eaves roofs. The west tower has a slate saddleback roof with crowsteps and obelisk finials that were added in 1836. It includes narrow bell chamber loops and a cambered head west door, with exposed voussoirs above a similar doorway. The nave has broad transepts adorned with raking battlements and crude shoulder and apex finials. The slate coping beneath the battlements is slightly returned, resembling a schematic open pediment, which is echoed by a similar slate hood over the three-light traceried pointed windows. There are matching pointed-head two-light windows on each side of the transepts and an elaborate red brick star-shaped chimney at the northeast angle of the nave. The chancel features a hoodmoulded flat-headed two-light south window and a four-light east window. Late 18th century and 19th century tomb slabs are attached to the south wall.

The churchyard is large and contains plain granite piers at the entrance, scattered headstones, and some table tombs, including three in an iron-railed enclosure to the east of the chancel. There is also an iron-railed enclosure in the northwest corner with headstones belonging to the Harries family.

Inside, the nave and chancel are plastered and have three-sided roofs. The walls and roofs are divided into panels by applied timber strips, with a brattished wallplate. There is a carved wood screen leading to the north transept vestry, a finely carved chancel screen, and a full set of pews with octagonal colonettes on the bench ends, all dating from 1891. The matching pulpit is from 1906, along with choir stalls and reading desks. The sanctuary features encaustic tiled flooring and clear lattice glazing.

A notable feature is the fine 15th or early 16th century decagonal stone font, which has reversed shield plaques, one displaying the arms of Sir Rhys ap Thomas, who died in 1525. The font has a modern base. In the northeast corner of the nave, there are some plain plaques commemorating the Harries family of Trevaccoon: John Harries of Cryglas, who died in 1797 by H Wood of Bristol; Samuel Harries, who died in 1839; and J H Harries, who died in 1869.
