Radyr () is an outer suburb of Cardiff, about northwest of Cardiff city centre. Radyr is part of Radyr and Morganstown Community, for which the 2011 Census recorded a population of 6,417. Morganstown is north of Radyr, on the other side of the M4 Motorway. Neighbouring communities are Whitchurch to the east on the opposite bank of the River Taff, Pentyrch to the west with St Fagans and Llandaff to the south. History Stone Age until the Norman Conquest Evidence of Stone Age occupation of the Lesser Garth Cave near Morganstown was discovered in 1912 and included worked flints. In 1916 excavation of a mound of in Radyr Woods revealed charcoal and Iron Age pottery. Radyr developed after the Norman invasion of Wales at the start of the 12th century and formed part of the Welsh Lordship or cantref of Miskin under the Lordship of Glamorgan created by the Norman King, William Rufus, in 1093. Origin of the name Hints about the derivation of the name Radyr can be found in Lifris's writings Life of St Cadog, written between 1081 and 1104 but relating to the earlier period around AD 530, which mentions a croft or tref on the site called Aradur Hen. Lifris also tells the story of Tylyway, a hermit who was held to have lived on the banks of the Taff. Tylyway's cell is the most likely origin of the name Radyr; from the Welsh yr adur, meaning "the chantry", although Arudur Hen is also possible. Norman occupation and Middle Ages The Norman motte in the "mound field" is a flat-topped mound in diameter at the base and high, surrounded by a ditch wide. An adjoining bailey to east of the motte could indicate the boundary between Norman and Welsh land. The motte was surrounded by a timber palisade around a wooden keep and formed part of a defensive line with similar mottes at Thornhill and Whitchurch. The early settlement that became Radyr developed around the Norman church and manor house in what is now Danescourt. Surveys in 1307 describe an agricultural hamlet surrounded by arable fields. The 14th century Welsh Lord of Radyr, Cynwrig ap Hywel, followed by his descendants, farmed the area until it was devastated by the Black Death and by battles between the Marcher Lords in 14th and 15th centuries when the whole area was laid waste.
