<P> Concentric castles were expensive to build , so that only the powerful military orders , the Hospitallers and Templars , or powerful kings , could afford to build and maintain them . It has also been pointed out that the concentric layout suited the requirements of military orders such as the Hospitallers in resembling a monastery and housing a large garrison . Such castles were beyond the means of feudal barons . Thus concentric castles coexisted with simpler enclosure castles and tower keeps even in the crusader states . </P>
