Barmouth (Welsh:Abermaw (formal); Y Bermo (colloquial)) is a town in the county of Gwynedd, north-western Wales, lying on the estuary of the River Mawddach and Cardigan Bay. Historically in Merionethshire, the English form of the name is derived from "Aber" (estuary) and the river's name "Mawddach"
