The art of the Crusades, meaning primarily the art produced in Middle Eastern areas under Crusader control, spanned two artistic periods in Europe, the Romanesque and the Gothic, but in the Crusader kingdoms of the Levant the Gothic style barely appeared. The military crusaders themselves were mostly not noticeably interested in artistic matters, or sophisticated in their taste, and much of their art was destroyed in the loss of their kingdoms so that only a few pieces survive today. Probably their most notable and influential artistic achievement was the Crusader castles, many of which achieve a stark, massive beauty. They developed the Byzantine methods of city-fortification for stand-alone castles far larger than any constructed before, either locally or in Europe.
