In the last episode of Waldemar Januszcak‘s excellent television series on the mostly unheralded art of the Dark Ages, where he covered the Vikings, the Carolingians and The Anglo-Saxons, he referred to Lindisfarne (Holy Island) as being off the North coast of Britain.
Tut-tut, Waldemar. That would make it in the Pentland Firth/Atlantic!
Lindisfarne is actually barely two-thirds of the way up Britain.
It is, however, off the North-East coast of England.
