It was indeed a strong place. The castle itself was perched upon the edge of a precipitous cliff, which on three sides of it fell away almost perpendicularly. On the other side, the approach, though steep, was more gradual. In front of the castle was a large courtyard. Inside and at the foot of the side walls, which rose apparently sheer from the edge of the precipices, were the quarters of the garrison. The end wall was very strong and massive, with a flanking tower at each corner and another over the gateway. At its foot the rock had been cut away perpendicularly, forming a dry moat some twenty feet deep and forty wide. On the other side of the moat was a similar enclosure open towards the castle, but larger and with even more massive walls, with strong flanking towers at short distances apart. Here the vassals would drive in their cattle and herds on the approach of a hostile force. This exterior fortification was in itself unusually strong, and would have to be taken before the second wall could be attacked, as it could only be approached on that face. "It is a strong place, indeed," the count said at last. "It would be necessary to scale the outer wall, and, even could this be done by stealth, there would be that deep cut and the next wall to cross, and the castle itself, which is indeed a fortress, to enter; a well-nigh impossible undertaking." "I do not think it would be necessary to scale the wall of the outer court, my lord, for there is open ground on either side, as far as the point where the cut is made. Beyond that, methinks, there will be space enough to walk between the edge of the rock and the wall. The castle itself is most likely so built that the cliff goes sheer down from its foot, but I do not think that is so with the wall of the courtyard. There would be no occasion for it; the bravest men would not venture upon a narrow ledge where they could be overwhelmed by stones or missiles from the wall above." "I think that is so, Johann; but at any rate that cut would have to be passed. No, the castle is impregnable save by stratagem, or treachery within, or against an army with battering-machines. 'Tis stronger than I thought it; I never took so good a look at it before, for it was but seldom that I rode in this direction." "It would need an army," Johann agreed, "and might well cost the loss of a thousand men."
