HOLY-Island, a small island lying on the coast of England, six miles south of Berwick, in Northumberland. It is not above two miles and a quarter in length, nor much above a mile in breadth. The soil is rocky and full of stones, for which reason it is thinly peopled: it has but one town, with a church, and a castle, under which there is a commodious harbour, defended by a block-house.
