Pen Dinas is the name of a large hill within the boundary of the village of Penparcau, on the coast of Ceredigion, Wales, upon which an extensive Iron Age, Celtic hillfort of international significance is situated.
The name is more correctly 'Dinas Maelor', this could be translated into English as 'Maelor's Fort' or 'Maelor's City'. Tradition refers to it as being the fort of the giant Maelor Gawr. Pen Dinas strictly speaking only refers to the highest point, 'Pen y Dinas' or 'Head of the Citadel',. The southern summit is also where, in the Bronze Age, a burial mound was erected.
