The parish church of St Mabyn dates largely from the late 15th century, although it stands on the site of a much earlier building. It was heavily restored in the late 19th century. The wagon roof over the nave, chancel and both aisles are original and feature carved wall paltes and bosses. There is a piscina in the chancel and both aisles and the rood loft stairs (now disused) can be seen in the north wall behind the pulpit.
