Betws-y-Coed is one of the honeypot locations in Snowdonia. It 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 London to Holyhead road (now the A5) 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.
