St Teilo's church has an early foundation, possibly dating back to the sixth century. The present nave probably dates to the fourteenth century and the chancel to the fifteenth. E V Collier undertook some work at the church in 1897, especially at the tower, which was 'largely rebuilt with square-headed openings in contrasted red sandstone.'
Cadw describes the exterior as: 'Nave, chancel under lower roof line, large south porch, large west tower with pyramid roof. Rubble stone, stone tile roof. Two-light cusped windows throughout with large east window in local Perp style. Several wall tablets on east wall. Priest's door and south door have chamfered pointed arches. Porch has stone benches, stoup and fifteenth century roof timbers, including one arch-braced truss and one with cusped decoration.'
Inside, the 'nave roof has barrel profile, probably fifteenth century, with wide chamfered ribs and carved bosses. Nineteenth century boarded infill and replacement bosses. Plastered pointed chancel arch; chancel has brattished wall plates, seventeenth communion rails and piscina. Fourteenth century octagonal font, re-used C17/C18 dado panelling, nineteenth century furnishings including vestry screen along west end. Tile and wood floor. In vestry primitive wood chest on legs. Three bells.'
It is Grade II* 'because of the largely medieval fabric in a fine rural location.'
