Spectacularly sited Harlech Castle seems to grow naturally from the rock on which it is perched. Like an all-seeing sentinel, it gazes out across land and sea, keeping a watchful eye over Snowdonia. The English monarch Edward I built Harlech in the late 13th century to fulfil this very role. It was one of the most formidable of his 'iron ring' of fortresses designed to contain the Welsh in their mountain fastness. Ironically, in 1404 it was taken by Welsh leader Owain Glyn Dwr who proceeded to hold a parliament here.
