Parish Church of St Tydecho, Foel

The parish church of St Tydecho is a building of axe-dressed local slatey stone with a slate roof and decorative crested tile ridge. It likely dates to the 19th century with original masonry incorporated into the north, south, and especially the west walls, although the chancel and general heightening of the walls are also from the 19th century. The roof is 19th century and tall, with a west bellcote roofed with slate slabs and carrying an iron weathervane.

The church appears externally as a single chamber, featuring a single-bell bellcote, a south porch, and a small north vestry. The east window is in simple Perpendicular style, composed of three main lights, and is surmounted by a circular slate marking the rebuilding of the church in 1862, along with a stone finial cross. A two-light window with trefoiled round-headed lights, possibly contemporary with the east window, is found on the south side of the chancel. The 19th-century restoration added two windows to the south side and three to the north, all timber Gothic windows with trefoil-headed lights and generously projecting slate sills.

The porch contains side benches and outer double doors, with a small pointed window on the east side, now blocked. The vestry has plain, uncrested ridge tiles, a single light to the north, and a boarded east door.

Inside, the church is entered through the south side of the nave. The interior has a largely 19th-century appearance, characterized by a long, narrow layout with a step up to the chancel, which is also distinguished by thicker walls. The nave roof consists of four bays with braced collar beam trusses, while the chancel features a slightly irregular barrel ceiling. There are two banks of simple late 19th-century pews, and a pulpit is located on the right, opposite a small organ. The west gallery may be earlier, particularly in the section built around the original masonry. It is of moderate height, with closed-in storage space beneath, and the front of the gallery displays simple Gothic carving below the top rail. The back wall of the gallery is boarded. An octagonal font, perhaps from the 15th century, sits in the pew nearest the south door, resting on its original base, though the top has been altered with a carved 19th-century inscription. A marble memorial to those lost in the First World War is affixed to the north wall against a black ground. The small chancel includes an altar, reredos, and side panelling, all with simple oak carving.
