St Tecwyn's Church is thought to be medieval in origin. An eleventh century inscribed stone is incorporated into the present church building. The inscription has been interpreted as 'the Cross of St. Tecwyn, presbyter, to the honour of God and the most illustrious servant of God, Heli, deacon, made me. (the last word may read 'merci')'. Another medieval stone, whose pattern includes a linear Latin cross with a lozenge shaped ring at its upper end, is one of only four definite examples in Wales.
