Description

The Church of St Tyfaelog is a small church constructed in the Early English Gothic Revival style. It was built of snecked rock-faced sandstone with red brick dressings and banding, and has a very deep roof of Welsh slate with overhanging eaves that sweep down low over the aisles, finished with metal cruciform finials. The plan includes a nave with aisles on each side, a steeply gabled west porch, and a chancel with a curved apse.

The church's architecture is characterized by mostly lancet windows with moulded brick hoods. At the west end, three lancets are partially masked by the porch ridge, flanked by buttresses with offsets, and topped with a small circular light containing pierced tracery; smaller lancets are located at the ends of each aisle. The steeply gabled porch features a two-order pointed archway and a double door with decorative hinges, with a quatrefoil above. To the side aisle walls are three sets of paired windows, with a single lancet at the east end; buttresses mark the junction with the chancel. The chancel roof is conical over the apse and slightly stepped down. The apse, at the east end, has three lancets spaced closely under the eaves. The ground level changes here, resulting in a taller building showcasing five rows of banding.

The interior is polychrome, featuring contrasting banded brick, painted render, brick, and stone. It has a boarded roof, more decorative and cusped over the chancel, along with remnants of fittings for former gas chandeliers. The floor is reportedly partially made from railway sleepers. Pointed-arch three-bay aisle arcades feature arches of contrasting red brick and white painted stone, with circular piers having moulded caps, clustered at the ends. A deep immersion baptismal pool of stone, brick, and tile, with an inset cross in the tiled floor, is located near the west door on the south side, along with a large, square-bowled font. A stone pulpit with open canopywork occupies the northeast of the nave, dating from around 1863. A war memorial is on the north wall. The chancel lacks a screen, and the chancel arch is represented by short piers rising from high-set corbels. The chancel is richly furnished with decorative crested wood panelling and choir stalls with poppy heads, refurbished around the time of the First World War. A large organ from 1926 is set back within a two-bay south choir arcade. Within the sanctuary, the altar incorporates a carved frieze depicting the Last Supper; niches with figures of saints are situated at the rear, topped by tall crocketed pinnacles. Above the three pointed-arched windows with stained glass (likely dating from around 1917, possibly by R.J. Newberry, as is also found in the nave), is a painted inscription. A richly carved two-bay piscina is set into the south wall. The porch, at the west end, features a three-ordered pointed inner arch.
