History It is most notable for St Illtyd's Church, a 13th-century building generally believed to have been built by Cistercian monks from Llantarnam on the site of a previous church which historians have tended to date as dating from 863 AD or thereabouts. The present dedication to St Illtyd is not however the original one, for it was not until around 1754 that this saint's name was given as the name of the church. The 9th century "Englynion y Beddau" (Stanzas of the Graves) collected among the texts now known as the Black Book of Carmarthen (recorded 12th-13th centuries) refer to "Llan Heledd" or "Llan Helet", (Heledd being a sixth to seventh princess of Powys and a "local canonisation". T. D. Breverton records that during the 16th and 17th centuries the parish of Llanhilleth bore the name Llanheledd Forwyn (Church of Heledd the Virgin), and this dedication has survived today in the place-name, having reached its present form via Llan Helet, Llanheledd, Llanhiledd and Llanhylithe down the years, although Llaniddel is given by Archdeacon Coxe in 1701 as the name of the parish and there are references to the church as being dedicated to "St Ithel" until around 1800. Until 1911 it was the parish church of Llanhilleth, now in the Diocese of Monmouth, and it remained in intermittent use as a place of worship until 1975.
