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', (upon which the Wellington Monument now stands). The southern summit is also where, in the Bronze Age, a burial mound was erected.
