Criccieth Castle

Perched on a rocky headland between two sweeping beaches, Criccieth Castle is one of the most dramatically located castles in Wales. Overlooking Tremadog Bay and the mountains of Eryri beyond, the fortress dominates the skyline of the charming seaside town of Criccieth. Built during the 1230s by Llywelyn ap Iorwerth, better known as Llywelyn the Great, it was later expanded by his grandson, Llywelyn ap Gruffudd, the last native Prince of Wales. One of the castle’s most impressive surviving features is its massive twin-towered gatehouse, which still stands close to its original height. Visitors can also explore the remains of the inner and outer wards, sections of the curtain walls, and the foundations of towers that once formed a formidable coastal stronghold. The elevated position provides spectacular views across Cardigan Bay, making the scenery as memorable as the history itself. Criccieth Castle played an important role in Welsh history. It served as a residence, administrative centre, and even a prison for high-ranking captives during the rule of the Welsh princes. Following the conquest of Wales, Edward I captured and strengthened the fortress, adding improvements to its defences. Despite these enhancements, the castle was eventually attacked during the uprising of Owain Glyndŵr in 1404, when much of it was damaged by fire and left to decline into ruin.
