Charles Henry Ashdown, British Castles
“ Bamborough Castle, grim, grey, and imposing, by its vastness and massive proportions, stands upon a rocky height of igneous formation on the coast of Northumberland. It is by nature a promontory fortress, and as such was seized by Ida and his Angles in 547, and who thence extended his sway over what subsequently became the kingdom of Bernicia. The castle is mentioned in 774, and was twice taken by the Danes. In 1095 the dramatic siege occurred with which Bamborough will be for ever associated. ”
