Harlech Castle is a formidable medieval fortress built by English King Edward I between 1283 and 1290 as part of an 'iron ring' of castles intended to subjuct Gwynedd in northwest Wales. Constructed in just seven years under the guidance of Master James of St George, the castle showcases advanced concentric architecture inspired by Crusader fortifications. Set on a dramatic cliff overlooking Cardigan Bay within Snowdonia National Park, its 'walls within walls' design maximizes natural defensive advantages. The castle witnessed pivotal moments in Welsh and English history, including occupation by rebel leader Owain Glyndŵr in the early 15th century and its famous last stand during the Wars of the Roses in 1468, commemorated in the battle song 'March of the Men of Harlech.' Today designated a UNESCO World Heritage Site, the castle remains a powerful symbol of medieval military architecture.
