Other information

Carreg Cennen means ‘rock next to (the river) Cennen’ with carreg ‘rock’ followed by the river name. Cennen rises near Blaen Cennen on the Black Mountain and flows into Afon Tywi near Ffair-fach. Cennen may consist of the element cen ‘lichen’ followed by a diminutive suffix ‘-en’ refering to the river. Lichen frequently features on local limestone. Alternatively it is possible that Cennen is a personal name that has been adopted as a river name. The nearby castle belongs to the late 13cent./early 14cent., but there is evidence of earlier fortifications.
