Church of St Tanwg

The Church of St Tanwg is a medieval parish church featuring a continuous nave and chancel, with a single bellcote at the west gable. It is constructed from roughly coursed rubble masonry, using large stones for the quoins and stone dressings. The roof is made of slate and has rough stone copings. The entrance is located at the west end, accessed through a pointed arched doorway with radiating quoins. Above the entrance, scars in the masonry indicate that there was once a gabled porch. The east window was originally a tall pointed arched window, but now only the moulded label with facial stops remains, as the opening has been partially blocked and replaced with a 3-light mullioned window.

On the south lateral wall, there is a blocked opening at the west end with an arched head of radiating quoins and an advanced stone label. At the east end, there are two rectangular openings with paired timber framed lights. The north lateral wall features a partially blocked doorway at the west end, which now contains a rectangular window with cusped trefoil lights and a square hoodmould with weathered facial stops; there is a blocked window to its right.

The nave and chancel are undivided, and the roof consists of six bays supported by arch braced collared trusses. The three easternmost bays have cusped windbraces, and the eastern bay shows signs of a former barrel roof over the sanctuary. There is a weathered cross beam that once formed the top of the rood screen at the east end, and at the far west end, there are gallery support beams that were formerly part of the choir loft, featuring rounded moulded soffits. The sanctuary has a plain rail and is raised by a single step. Within the sill of the south sanctuary window is part of a 6th-century gravestone inscribed with the words "EQUESTRINOMINE." Another inscribed stone lies by the altar, bearing two names: the first reads "INGENI," while the second is defaced but may read "ENNB..." (for "ENNBAR"). Additionally, part of a gravestone is built into the west gable above and to the right of the doorway, likely dating from the 7th to 9th centuries. This stone features a roughly incised cross and has the initials and date "REP 1685" added, probably when the doorway was inserted.
