Cwmfelin Mynach is a tiny Carmarthenshire village. It has a population of only 64 residents. Cwmfelin Mynach means Valley (cwm) of the Monks' (Mynach) Mill (Felin). It was founded in the 6th century by the Cistercian monks, or Whitefriars, who had a monastery in nearby Whitland. The river Gronw which starts at Blaenwaun (one of the highest inhabited villages in the West Wales peninsula) runs through Cwmfelin Mynach. In the medieval period the river was used to drive a corn mill. The river was also used for Baptisms.
