Both the Great and Little Ormes have been etymologically linked to the Old Norse words urm or orm that mean sea serpent (English worm is a cognate). One explanation is that the Great Orme is the head, with its body being the land between the Great and Little Ormes, whilst another, possibly more likely, is that the shape of the Great Orme viewed as one enters the isthmus of Llandudno from the SE landward end resembles a giant sleeping creature. The Vikings left no written texts of their time in North Wales but they certainly raided the area. They did not found any permanent settlements, unlike on the Wirral Peninsula, but some Norse names remain in use in the former Kingdom of Gwynedd (such as Point of Ayr near Talacre).
