The Norman church was cruciform and additions were made in the 13th and 14th centuries; during the 15th century the south aisle and tower were completed and the church was embellished with fine woodwork and stained glass. Though considerable restoration took place in 1848 much of the late medieval woodwork and glass remains. In a field opposite the church is the holy 'Jordan Well' used for divination, and until comparatively recently, for baptism. The Anglican benefice is united with those of Saint Clederus, St Clether, and Altarnun.
