At one spot only in the rocks above is there a gap, and through that gap, probably once walled up, access is obtained into a sort of circular courtyard, where there are traces of a fireplace, and where is a stone bench. From this court a spiral staircase, rock-hewn, leads to the platform on top of the rocks. In the wall on the right of the court is a doorway neatly cut in the chalk, square-headed and adapted for a framed door that could be strongly barricaded. Immediately within is a quadrangular pit sunk in the floor, now choked with stones. This, in such a position, could not be a silo, it probably was the opening through which those who entered the cave from below, by the road, made their way into the interior of the fortress. Stepping over this pit one enters a hall with six large round holes cut in the roof communicating with an upper chamber, and receiving a borrowed light through them. A spiral staircase at the side furnished with _meurtrières_ through which the besieged could stab at their enemies, leads to the upper hall or chamber, which is lighted by two rude windows, one high up, the other low down, and with a bench recess opposite them. But the strange and perplexing feature of this room is that it has in the floor eight round holes, each large enough to let a man fall through. Six communicate with the chamber below, but the other two open under the overhanging cornice, outside the castle. One of the holes--opening into the nether chamber, is precisely where would rest the feet of men seated on the bench. There is no trace of a groove to receive covers to these holes.
