Spectacularly sited Harlech Castle rises from a rocky promontory, watching over Snowdonia. The English monarch Edward I built Harlech in the late 13th century to fulfil this very role. Ultimately, the castle fell to Welsh national hero, Owain Glyndower, in 1414, inspiring the anthem "Men of Harlech".
The castle, along with Edward I's other 13th century walls and fortifications in North Wales, is part of Snowdonia's UNESCO World Heritage Site.
