Llangarron is a small village and civil parish in southwest Herefordshire within of both Ross-on-Wye (Herefordshire, England) and Monmouth (Monmouthshire, Wales).[1] The population of the civil parish at the 2011 census was 1,053.[2] The civil parish includes the settlements of Llangrove, Llancloudy, Biddlestone and Three Ashes.[3] The church is dedicated to St. Deinst (a Celtic saint who died in c584). The village no longer has a post office nor pub, though it does have a community hall.
The name, also spelt Llangarren and Llangarran, refers to the Garron Brook, a tributary of the River Wye. Several local farms have Welsh names, a legacy of the fluid nature of the England-Wales border in the past. A variant suggestion is that the name derives from “garan”, Welsh for stork or heron, as a heron-like bird is depicted in the church gates.[4]
See main article: Church of St Deinst, Llangarron. The dedication to 'St Deinst' exists for no other Anglican church. It is identified with St. Deiniol, or Deiniel, a sixth-century abbot-bishop and founder of a monastery at Bangor and to whom the mediaeval Bangor Cathedral was dedicated. Records of a church at Llangarron begin in the reign of Edward the Confessor, when a church was consecrated at the site, and a subsequent re-consecration as "lan garan" church is recorded in the reign of William I.[4]
Other buildings of note in the parish, all of which are Grade II* listed, are Langstone Court, a late seventeenth-century red-brick house, Ruxton Court, an Elizabethan stone and half-timbered farmhouse, and Bernithan Court, which was built in about 1960 on the foundations of an older house.[5]
An electoral ward in the same name exists. This ward stretches towards Ross-on-Wye with a total population taken at the 2011 Census of 3,357.[6]
