>The article describes the fortified building. See also castle (disambiguation) A castle (from the Latin castellum, diminutive of castra, a military camp, in turn the plural of castrum or watchpost), is a fort, a camp and the logical development of a fortified enclosure. The term is most often applied to a small self-contained fortress, usually of the Middle Ages, though traditionally in Britain it has also referred to prehistoric earthworks (e.g. Hollingbury Castle, Maiden Castle). "Castle" sometimes denotes citadels (such as the castles of Badajoz and Burgos) or small detached forts d'arrêt in modern times. In Spain, a fortified dwelling on a height for the administering authority retains its Moorish name of alcázar (see illustration, right).
