What is "cerrigydrudion"

Cerrigydrudion, sometimes spelt Cerrig-y-drudion, is a village and community in Conwy, Wales. Until 1974 it was part of the historic county Denbighshire, when it became part of the newly formed county of Clwyd. When the county of Clwyd was abolished in 1996, the village was transferred to the new Conwy County Borough. The village formerly lay on the A5, but a short by-pass now takes the road along the south-western edge of the village. Prior to the by-pass being built, Cerrigydrudion was the highest village on the A5 between London and Holyhead.
