St Enghenedl's Church, Llanynghenedl, is a former parish church in Anglesey, north Wales, dedicated to the son of a 6th-century King of Powys. According to the 19th-century antiquarian Angharad Llwyd, the first church in Llanynghenedl was erected in about 620. A new church was erected in 1862, replacing a building that the 19th-century clergyman and antiquarian Harry Longueville Jones noted as dating in part from the late 13th or early 14th century, based on the decorations on the south doorway. The church later fell into disuse as a result of the growth of the nearby village of Valley and the church there. In 1988, St Enghenedl's was dismantled and re-erected as an extension to St Mihangel's, Llanfihangel yn Nhowyn, so that St Mihangel's could serve as the church for RAF Valley. The forme
