Parish Church of St Illtyd

The Parish Church of St Illtyd comprises a defensible medieval west tower, largely rebuilt aisle-less nave, a south porch, a north vestry, and a narrower chancel. The church dates to the medieval period, with significant rebuilding in the 19th century. It is constructed of random rubble masonry, with some 19th-century snecked and coursed work. The roofs are gabled and slate-covered, with a lower pitch to the chancel. Raking gable parapets are present on kneelers.

The west tower is three-stage, featuring a crenellated parapet on corbels, later copings to the merlons. The bell stage has single-light openings with arched stone lintels and chamfered reveals. Slit-like openings are present on the first floor, and a string course runs around the tower. The ground floor is splayed, and an early 16th-century window features two rounded lights, a central mullion flanked by wheel motifs and a Tudor rose, all beneath a drop-ended label. A broad west door has a two-order depressed arch with a hoodmould. A slit-like window to a vice links the nave to the tower on the north side. The nave has raised eaves. A 19th-century gabled south porch has a cross finial, clasping buttresses, a moulded round arched doorway with a hoodmould and heads to stops, and a Caernarfon arch under a pointed tympanum to the inner doorway. A Welsh inscription from 1859 commemorates the church's rebuilding. The nave has two round arched windows, each with a hoodmould and heads. Reset early 17th-century tombstones of the Evans family of Eaglesbush are incorporated into buttress-like projections to the right of the porch. C18 moulded labels and brackets are found on the exterior. The north wall windows lack hoodmoulds. A 19th-century gabled vestry is added to the north side.

A blocked priest's door to the south of the chancel is round arched and constructed from stone voussoirs. Round arched windows are present on the sides of the chancel, along with a tall round arched lancet to the east window. Two 18th-century grave slabs are set into the wall to the left of the east window, recessed under hoods on brackets.

An 18th-century depiction of Royal Arms is positioned above a low, narrow, whitewashed medieval chancel arch, which is in the early Romanesque tradition. The arch is formed by freestone and rests on simply moulded impost blocks. A medieval, whitewashed cusped niche is re-used to the left of the east window, and 18th-century altar rails feature cannon barrel balusters.

Inside the church, a barrel vault forms a passage to the west door under the tower. A rectangular "window" is present on the first floor, looking into the church. A later vice doorway is located in the northwest corner of the nave. The nave has a boarded roof with scissor trusses. A good Romanesque D-shaped tub font, with a rope-moulded rim, stands on a later pedestal. A two-decker pulpit dates to 1859. Numerous wall monuments are found in the nave, including one from 1768 commemorating Ann Bevan, featuring a relief of a Lamb and Flag, with some paint remaining, and another from 1819 commemorating Mary Anne Gwyn, with a slate pediment on fluted pilasters. A significant number of monuments were created by P Rogers of Swansea between 1819 and 1860.
