Barmouth is a community as well as community in the region of Gwynedd, north-western Wales, lying on the tidewater of the River Mawddach as well as Cardigan Bay. Found in the Historic county of Merionethshire, the Welsh type of the name is derived from "Aber" (estuary) as well as the river's name, "Mawddach". The English kind of the name is a corruption of the earlier Welsh form 'Abermawdd'. The community is served by Barmouth train station. The town grew around the shipbuilding market, and also extra lately as a seaside hotel. Significant buildings include the middle ages Ty Gwyn tower house, the 19th century Ty Crwn roundhouse jail and also St John's Church. William Wordsworth, a site visitor to Barmouth in the 19th century, defined it thus: "With a great sea sight in front, the hills behind, the wonderful tidewater running 8 miles [13 kilometres] inland, as well as Cadair Idris within compass of a day's walk, Barmouth can constantly hold its very own versus any rival." Dinas Oleu (Citadel of Light), which lies east of the community on the adjacent hill, was the very first system of land to be given away to the National Trust fund.
