The History of Rhiwbina’s Street Names


Rhiwbina takes its name from the small hamlet and farm that once sat on the hillside of the Wenallt.

The name itself has been the topic of much discussion but there are several theories. The main theory and possibly one of the earliest is found in the Book of Llan Dav. The document– the Riu Brien dates from the 11th century and is a collection of records from nearby Llandaff Cathedral. Rhiwallon stabbed a friend– a member of the Bishop’s household. He was ex-communicated and expelled before making amends with the Bishop, and with King Hywel’s blessing, the Bishop returned to Riu Brien– his inherited land. Other theories vary from the Welsh versions of hill of pines to stories of local monks.

The local street names however are a more recent addition. Here is a list of most of them.
