Classical Architecture


Architecture Dictionary: K



A term almost synonymous with donjon., the principal tower of a castle, usually placed either in the centre, or in one angle of the inner-court, or ballium. The oldest keeps were usually erected on the summits of artificial mounts, the doorways being attained by flights of steps. The forms of keep-towers were various. That of Conisborough Castle is nearly circular, strengthened externally with buttresses, and is, in many respects, the most interesting, as well as the most ancient, building of its class remaining. That of Windsor also approaches the circular form. Those of the Tower of London, and of Rochester Castle, are nearly square; and the plan of that called Clifford’s Tower, at York, is formed by portions of four circles; the building presenting externally the appearance of four cylindrical towers in conjunction. Keep-towers were generally divided internally into several stories: and, in those of large dimensions, each floor was again subdivided into two, or more apartments.


The lowest of these was mostly used as a dungeon for prisoners; others were devoted to the reception of military stores and instruments of war; and near the top of the keep were the apartments of the castellan, or governor. A Well and a Chapel were almost universal accompaniments to the keep. The perfection to which the art of fortification was formerly carried, is fully manifested by an inspection of the numerous keep-towers of Great Britain. The late Edward King, in Munimenta Antigua, and in his Observation on Ancient Castles, in the fourth and sixth volumes of the Archceologia, has noticed and described some of their pecu¬liarities. Woolnoth's Ancient Castles, and the fourth volume of the Architectural Antiquities of Great Britain, may also be referred to as containing representations and descriptions of several of these buildings
