Lisburn Castle (1) (Castle of Lisnagarvey, O'Neill's Castle in Lisburn, Conway Castle) None Castle - "Very imposing was the appearance of the deposed O'Neill's residence which consisted of an immense pile of buildings situate on a mound that overlooked the valley through which the River Lagan ran and in its outward aspect seemed rather like some place of defence rather than the home of an Irish Prince. In its architecture the leading features were castellated turrets and high-peaked gables while right above the windows were numerous loopholes from each of which projected the muzzle of a cannon. The interior of the Castle, its living rooms, dormitories and audience chambers exhibited little, either in form of promotion or of comfort, carved panellings marked the finish of each apartment, and, as wood formed the principal fuel, the hearths occupied very large spaces."
