Church of St. Edeyrn

The Church of St. Edeyrn is a Perpendicular style church, largely dating from the 15th century, with additions and alterations made in subsequent centuries. It features a nave of five bays, an added chancel to the east, a north transept, and a southwest porch. The church is constructed from local rubble with sandstone dressings, and has a modern slate roof with stone copings. A bellcote sits atop the west gable, and crosses are positioned at the east ends of the nave and chancel, and on top of the porch.

The south side of the nave has Perpendicular windows of one, two, and three lights. Several of these windows are resets from the 15th century, while others date to the late 19th century. The modern porch has an outer, segmental arched doorway with two chamfered orders, a lambs tongue stop, a moulded label with floriate stops, and a relieving arch. The original 15th-century inner door has a pointed head within a square frame, a moulded label, casement moulded jambs, and sunk trefoils in the spandrels. The north wall of the nave contains reset 15th-century Perpendicular windows, a 19th-century window, and an early 14th-century pointed doorway with ovolo moulded jambs. A reset 15th-century gallery window is set into the west gable. The chancel has a reset 15th-century window in the east gable with three trefoil lights, panel tracery, ovolo moulded jambs, and a moulded label. The south chancel window is a 19th-century design with three cinquefoil lights and panel tracery. The north transept has 19th-century windows of two and three lights.

The roof features exposed arch-braced trusses, with some reused late medieval timbers. The chancel and north transept are linked by pointed arches with single chamfered orders. The chancel is raised two steps and separated from the nave by a low screen of 17th-century softwood panels with floriate carving under an acanthus leaf frieze, and a moulded rail. The central panels of the screen are pierced and slightly recessed. Similar carved panelling is found on the reredos, the upper part of the rectangular pulpit, and the facing panel of a reading desk. The sanctuary is further raised by three steps, and includes encaustic tiles on the second step riser bearing the inscription "WASH MY PASSION AWAY WITH INNOCENCE AT THE ALTAR OF THE LORD HERE." The moulded sanctuary rail is decorated with stanchions and brackets. An 18th-century gallery is located at the west end, with a turned balustraded front, accessible by a staircase, and supported by two oak crossbeams. One beam is inscribed "IB.RH.II.W.1777" and the other is a reused timber. The medieval font comprises a plain, octagonal straight-sided bowl set on an octagonal column and plinth. The pews are made of pitch pine, with three featuring brass plaques commemorating the Presaddfed family and one to the Mynydd y gof family.

The north transept window depicts St. Edeyrn, created by Mayer & Co. of Munich and London. The east chancel window depicts the Ascension, and the south chancel window has geometric designs, accompanied by brass plaques remembering Mary, wife of the Reverend Hugh Wynne Jones of Treiorwerth, who died in 1867, along with their children, Thomas (died 1856) and Jane (died 1851). The church contains 18th and 19th-century memorials.
