Church of St Llonio

The Church of St Llonio is a medieval building, largely dating from the 14th century, with 19th-century additions and alterations. The original structure is built of mixed uncoursed rubble with red sandstone dressings, believed to have originated from the Roman fort at Caersws. Later work incorporates greywacke rubble with limestone dressings, all under slate roofs with crested clayware ridges and gable crosses.

The church consists of a short chancel, an organ chamber, and a vestry located at the east end of the south nave. A 19th-century porch provides access to the medieval tower, which features a hollow-chamfered arch. The 19th-century windows include two-light windows with varied tracery and three-light square-headed windows with trefoil tracery, mirroring the style of earlier windows. A projecting stair is situated on the northwest corner of the sturdy tower, with a small medieval window. The upper stage of the tower was rebuilt, replacing a low timber-framed top, typical of eastern Powys, with a higher weatherboarded stage and pyramidal roof.

Inside the tower, the inner arch of the door is from the 13th century, characterized by a tall arris roll-moulding and an ill-formed pointed arch on chamfered imposts. The wide tower arch is 14th century, consisting of three chamfered orders. The nave walls are plastered, and a trussed rafter barrel roof covers both naves. An arcade of four bays features alternating four-shaft and octagonal columns supporting arches of two chamfered orders. The chancel roof is panelled. A 19th-century chancel arch sits upon corbels, and an arched opening on the south side houses the organ. Two medieval wall tombs are preserved within the north wall, along with a simple trefoiled piscina east of a 19th-century sedilia on the south side. A stone and wood reredos is also present. In the vestry, a triptych displays five carved wooden panels from the former timber arcade, portraying the Fall and the four evangelist symbols, assembled in 1865.

The fittings date primarily from 1865, with the organ being a later addition. The chancel furniture is boldly detailed, featuring panelled fronts with arches, strapwork, and gadrooning, raised two steps above the nave; the north-side set forward more recently. The pulpit, located on the north side, is a lobed, panelled octagon on a stone base. The font, situated under the tower, is 19th century, with the defaced 15th-century font (featuring quatrefoil panels) set behind it. A bell in the tower dates from around 1450.

The glass is all 19th century; the east window of the chancel depicts a Crucifixion by Clayton & Bell (1857). Other windows depict the Resurrection, Revelations, and St Paul explaining the gospels to Caractacus and Brav.

Monuments include a memorial to Pryce Davies of Maesmawr Hall (died 1852) on the north side of the chancel. Under the tower, five wall tablets, reset during the restoration, commemorate George Meares (died 1849), Jessie Meares (died 1842), Thomas Kissey (died 1849), Lousa Meares, and Edward Davies of Maesmawr (died 1668). A ledger slab is dedicated to Mary Thomas and John Davies (died 1727).
