The ancient tower of Geierstein, though neither extensive nor distinguished by architectural ornament, possessed an air of terrible dignity by its position on the very verge of the opposite bank of the torrent, which, just at the angle of the rock on which the ruins are situated, falls sheer over a cascade of nearly a hundred feet in height, and then rushes down the defile, through a trough of living rock, which perhaps its waves have been deepening since time itself had a commencement. Facing, and at the same time looking down upon this eternal roar of waters, stood the old tower, built so close to the verge of the precipice that the buttresses with which the architect had strengthened the foundation seemed a part of the solid rock itself, and a continuation of its perpendicular ascent. As usual throughout Europe in the feudal times, the principal part of the building was a massive square pile, the decayed summit of which was rendered picturesque, by flanking turrets of different sizes and heights, some round, some angular, some ruinous, some tolerably entire, varying the outline of the building as seen against the stormy sky. A projecting sallyport, descending by a flight of steps from the tower, had in former times given access to a bridge connecting the castle with that side of the stream on which Arthur Philipson and his fair guide now stood. A single arch, or rather one rib of an arch, consisting of single stones, still remained, and spanned the river immediately in front of the waterfall. In former times this arch had served for the support of a wooden drawbridge, of more convenient breadth, and of such length and weight as must have been rather unmanageable, had it not been lowered on some solid resting-place. It is true, the device was attended with this inconvenience, that even when the drawbridge was up, there remained a possibility of approaching the castle gate by means of this narrow rib of stone. But as it was not above eighteen inches broad, and could only admit the daring foe who should traverse it to a doorway regularly defended by gate and portcullis, and having flanking turrets and projections, from which stones, darts, melted lead, and scalding water might be poured down on the soldiery who should venture to approach Geierstein by this precarious access, the possibility of such an attempt was not considered as diminishing the security of the garrison. In the time we treat of, the castle being entirely ruined and dismantled, and the door, drawbridge, and portcullis gone, the dilapidated gateway, and the slender arch which connected the two sides of the stream, were used as a means of communication between the banks of the river, by the inhabitants of the neighbourhood, whom habit had familiarised with the dangerous nature of the passage.
