It was claimed by Geoffrey of Monmouth in the 12th century that the castle at Tintagel Head was where King Uther Pendragon seduced Queen Igraine of Cornwall, while her husband, Gorlois, was under siege at Dimilioc. King Arthur was thus conceived and Tennyson made the castle his birthplace. The castle was built on the site by Richard, Earl of Cornwall in 1233, to build on the Arthurian legends that were associated by Monmouth with the area and because it was seen as the traditional place for Cornish kings. The castle was built in a more old fashioned style for the time to make it appear more ancient. Cornwall was relatively untouched during the Roman occupation of Britain, however coins and pottery fragments found at the site indicate that the site, typical of a cliff-fort, was occupied in the third or fourth century. Two Roman milestones nearby indicate that a road led to the settlement. After the Romans left Britain, Celtic peoples did build a fortress on the site.
