The isle of Lindisfarne is a tidal island off the north-east coast of England. It is also known as Holy Island and constitutes a civil parish in Northumberland. Both the Parker Chronicle and Peterborough Chronicle annals of AD 793 record the Old English name, Lindisfarena, which means "[island of the] travellers from Lindsey", indicating that the island was settled from the Kingdom of Lindsey, or possibly that its inhabitants travelled there.
A tidal island is a piece of land that is connected to the mainland by a natural or man-made causeway that is exposed at low tide and submerged at high tide. Because of the mystique surrounding tidal islands many of them have been sites of religious worship, such as Mont Saint-Michel with its BenedictineAbbey. Tidal islands are also commonly the sites of fortresses because of their natural fortifications.
