Betws-y-Coed is a village and community in the Conwy valley in Conwy County Borough, Wales. It has a population of 534. The name Betws or Bettws is generally thought to be derived from the Anglo-Saxon Old English 'bed-hus' - ie. a bead-house - a house of prayer, or oratory. The earliest record of the name is 'Betus', in 1254.
Betws-y-Coed lies in the Snowdonia National Park, in a valley near the point where the River Conwy is joined by the River Llugwy and the River Lledr, and was founded around a monastery in the late sixth century. The village grew very slowly with the development of the local lead mining industry. In 1815, the Waterloo Bridge built by Thomas Telford to carry the A5 road across the River Conwy and through the village, brought considerable transport-related development. The village became a major coaching centre between Corwen (to the east) and Capel Curig (to the west) on the Irish Mail route from London to Holyhead, which led to the improvement of the roads south to Blaenau Ffestiniog and north to Llanrwst and Conwy. It is a primary destination for the purpose of road signs.
