Criccieth Castle

Ruined Criccieth Castle, perched on the seafront's most prominent headland, offers views stretching along the peninsula's southern coast and across Tremadog Bay to Harlech. Constructed by Welsh prince Llywelyn the Great in 1239, it was overrun in 1283 by Edward I’s forces and recaptured for the Welsh in 1404 by Owain Glyndŵr, whose troops promptly reduced it to the still-standing gatehouse and some broken walls.
