"LLANDDWYN, (or Llanddwynwen), an ancient parish and island, now part of Newborough, in the hundred of Menai, county Anglesey, 9 miles from Carnarvon, 20 from Beaumaris, its post town, and 3 from the Bodorgan station on the Crewe and Chester section of the London and North-Western railway. It is situated in a wild spot near the coast, at the extremity of Newborough Warren, and on Llanddwyn Point stands the Carnarvon lighthouse. In ancient times it had an oratory to St. Dwynwen, the daughter of Brychan Urth, the patron saint of lovers; also a Benedictine cell adjoining the Ffynnon, or St. Mary's Well, which was visited by contrite persons, who munificently contributed to the support of the monks."
