Criccieth Castle (Welsh: Castell Cricieth; Welsh pronunciation: [kastɛɬ ˈkrɪkjɛθ]) is a ruined thirteenth-century castle in Criccieth, Gwynedd, Wales. It is located on a rocky headland overlooking Tremadog Bay and consists of an inner ward almost surrounded by an outer ward. The twin-towered inner gatehouse is the most prominent remaining feature and survives to almost its full height, as does the inner curtain wall. The outer curtain wall, the inner ward buildings, and the castle's other three towers are significantly more ruinous, and in places survive only as foundations. The castle was begun in the 1230s by Llywelyn ap Iorwerth, the prince of Gwynedd, who probably built the inner ward and gatehouse. It was extended by his grandson, Llywelyn ap Gruffudd, who probably constructed the outer ward. The castle was captured by Edward I of England in 1283 during his conquest of Wales and afterwards repaired and improved, work which included heightening the towers and inner gatehouse. The castle was besieged in 1294–1295 during an unsuccessful revolt against English rule by Madog ap Llywelyn, and further repairs took place under Edward II in the early fourteenth century.
