A Short History of Radyr and Morganstown

The Parish of Radyr came into existence soon after the Norman Conquest of Wales around the beginning of the 12th century. From the Norman period we have St. John the Baptist’s church and the Morganstown Motte. This earthwork suggests that for a short period during the Norman Conquest the boundary between Norman lands and those of the Welsh princes ran along the foot of Caerphilly Mountain.

The area had had a long history before the Conquest. Archaeological findings suggest that the Lesser Garth Cave (behind the Ty Nant Inn) was inhabited from the Stone Age onwards.

Place name evidence suggests that dark age princes might have had a residence at what is now the golf course. The sixteenth green covers what was once Maerdy Cottage and the “Maer”, whose house this would have been, was an official at the court of Welsh princes.

Lifris’ “Life of St Cadog” written in the 11th century, but referring back to the period around 530 AD, also mentions a villa or a “tref” called Aradur Hen. Lifris also tells the tale of Tylyway a hermit who lived on the banks of the Taff and Tylyway’s cell is the most likely origin of the name Radyr; from the Welsh yr adur, meaning the chantry.

The Mathew family of Radyr Court became involved in ironworking in the Tudor period. There is even a suggestion that cannon made in the Mathew foundry at Gwaelod y Garth, found their way onto the Spanish Armada.

The five settlements

Although the parish has been made up of twenty to thirty scattered farms since the Norman Conquest there have been five settlements:

  • A small hamlet of three or four houses near to St. John’s Church, which almost certainly ended with the Black Death.
  • Groeswen. A second small hamlet of four or five dwellings at the junction of Heol Isaf and the Llantrisant Road. It gets its name from a white cross that would have marked the pilgrim route from Llandaff to the shrine of Our Lady in Penrhys. Interestingly, one of the dwellings – possibly the blacksmith’s shop – is shown as being in the middle of the road on the 1766 Plymouth estate map. It existed until the road was widened in the late 19th century.
  • Morganstown. This developed as a village for industrial workers in the early 19th century. Built on a farm called Ty’n y Berllan this was the first name for the village. It was then called Pentre and Pentrepoeth before becoming Treforgan and finally Morganstown. The only explanation for the name Morganstown is that Ty’n y Berllan farm was owned by a Morgan Williams.
  • Radyr. Modern Radyr grew up alongside the Taff Vale Railway marshalling yard and the station which took many of the early “docksmen” to their daily work.
  • Danescourt. A new development of the late 20th century. Its name comes from some unlikely administrative logic. Before the building of Danescourt there were two buildings in the area, Radyr Court Farm and Danesbrook House. The planners at County Hall put the two together to create Danescourt and unfortunately the area has no known links with the Danes.
