 The enormous black castle was effectively an upgraded successor to the Crusaders' 6080 King's Castle, with the same general layout and the same complement of soldiers - four archers, four axe/spearmen, and four knights on horseback.Like 6080, 6085 could be opened and closed using special "hinge" pieces, and snapped closed using a peg and hole mechanism; for 6085 this enabled it to combine with Knight's Stronghold and Black Monarch's Ghost (see below) to create even bigger super-castles.The big difference was that 6085 had black and grey bricks and octagonal turrets, compared to 6080's all-grey scheme and rectangular towers, while 6085 was also among the first sets to include the horse armor barding.
