Valley is a village near Holyhead/Caergybi on the west coast of Anglesey, North Wales. In Welsh it is referred to as either Y Dyffryn (meaning The Valley) or [Y] Fali (pronounced as Valley). Recent research, prompted by local opposition to the name of Y Fali, suggested that Valley may be a corruption of the Irish Bally (settlement), or Baile as it is spelled in Irish. There does not appear to be a traditional Welsh language placename for the village, and thus there has been a reversion to Valley of late. There is no actual valley as the area is very flat, although a dip in the land was created when the railway and bridge to Holy Island were constructed, and this may be the origin of the name.
