Criccieth Castle is a castle situated on the headland between two beaches in Criccieth, Gwynedd, in North Wales, on a rocky peninsula overlooking Tremadog Bay.
Construction on Criccieth began in the early 13th century at the behest of Llywelyn ap Iorwerth of Gwynedd, and was later continued by his grandson Llywelyn ap Gruffydd, Prince of Wales. Because of its strategic location, it was a focal point in the war between England and Wales — eventually it was captured by Edward I of England during his second campaign in North Wales (1282-1283).
