The +Alhambra+ is universally considered to be the masterpiece of Hispano-Moresque art, partly no doubt on account of its excellent preservation. It is most interesting as an example of the splendid citadel-palaces built by the Moorish conquerors, as well as for its gorgeous color-decoration of minute quarry-ornament stamped or moulded in the wet plaster wherever the walls are not wainscoted with tiles. It was begun in 1248 by Mohammed-ben-Al-Hamar, enlarged in 1279 by his successor, and again in 1306, when its mosque was built. Its plan (Fig. 84) shows two large courts and a smaller one next the mosque, with three great square chambers and many of minor importance. Light arcades surround the Court of the Lions with its fountain, and adorn the ends of the other chief court; and the stalactite pendentive, rare in Moorish work, appears in the “Hall of Ambassadors” and some other parts of the edifice. But its chief glory is its ornamentation, less durable, less architectural than that of the Cairene buildings, but making up for this in delicacy and richness. Minute vine-patterns and Arabic inscriptions are interwoven with waving intersecting lines, forming a net-like framework, to all of which deep red, blue, black, and gold give an indescribable richness of effect.

A, _Hall of Ambassadors_; a, _Mosque_; b, _Court of Mosque_; c, _Sala della Barca_; _d, d_, _Baths_; e, _Hall of the Two Sisters_; _f, f, f_, _Hall of the Tribunal_; g, _Hall of the Abencerrages_.] The Moors also overran Sicily in the eighth century, but while their architecture there profoundly influenced that of the Christians who recovered Sicily in 1090, and copied the style of the conquered Moslems, there is too little of the original Moorish architecture remaining to claim mention here.
