St John the Baptist Parish Church

St John the Baptist Parish Church is a Grade II* listed building constructed from rubble with minimal dressings, featuring a stone tile roof topped with a crucifix finial at the east. A rubble chimney stack is located at the south porch, which now serves as a vestry. The church has a five-bay nave with paired ogee cusped leaded windows, and a stone sundial, although the gnomon is missing, is set between the eastern two bays. The south porch includes paired ogee windows with voussoirs and leaded glass, and below it is a round arched door with a datestone from 1795. Another round arched door is found in the lean-to on the right. Above the double-doored west entrance, there is a narrow round arched window with voussoirs and impost blocks. A louvered roundel ventilator, which is partly blocked, is situated in the nave gable end above the chancel roof. The chancel features a similar doorway on the south side, a window of the same type on the north side, and a three-light cusped ogee headed window at the east, which is stepped up to the center. An old view from around 1870 shows a round arched window in a smaller chancel.

At the southwest corner, there is a crucifix-shaped tomb enclosed by railings. Gravestones are affixed to the south chancel wall, including one of the earliest, dedicated to Nathaniel Thomas who died in 1775. Many later 18th and 19th-century gravestones are positioned against the church walls. The churchyard contains a grand tabernacle shrine type monument on the south side, along with several monuments by W. Parker from the late 19th century. There is also an obelisk-type monument by D. Thomas and a classical pedestal monument erected by Caradog for his family. A vault belonging to the Roberts family of Gadlys is present as well. At the east end of the churchyard, between Nos 27b and 28a High Street, a reused panel of likely earlier 19th-century ironwork can be found.

Inside, the church has a rendered interior with arched and diagonally boarded ceilings supported by ribs that spring from semi-octagonal stone corbels, and a crenellated cornice. The pointed chancel arch leads to steps up to the sanctuary, which is enclosed by iron gates. The window recesses have cambered arches, and there is an octagonal font. The medieval south doorway is preserved within what is now the vestry; it likely dates from the 13th century rather than the 1189 period and is characteristic of West Country work with continuous roll moulding. The church retains some notable 19th and early 20th-century monuments, including one by Thomas of Brecon dedicated to the Scale Family of Llwydcoed and another in memory of the wife of W. T. Lewis of Mardy.
