I visit the Gower for a quick holiday every summer but have never visited this impressive-looking castle, even though it is very close to the place where we stay.
Fydda’ i’n ymweld â Phenrhyn Gŵyr am wyliau byr bob haf ond dw i ddim wedi ymweld erioed â’r castell urddasol yma, er ei fod yn agos iawn at ble’r ydyn ni’n aros.
