The inner ward, of which alone any buildings remain, is roughly quadrangular, about 100 feet square. Along the west or river front are the hall and withdrawing-room. On the south front is a half-round tower and a curtain. The east, or ravine, side is destroyed to the ground level, as is nearly all the north end, in which was the gate-house. The hall, 20 feet by 40 feet, was on the first floor. There was a store or cellar under it, of which the east and south walls are gone. Its entrance, and any light it may have had, were probably given on the court or east side. The hall had a timber floor. It was lighted by three windows in the west or river wall. Of these, the recess of one remains, with a rather low, pointed arch. A door in the north wall led into the withdrawing-room, and one at the south end into the mural tower. The east and south walls are gone. The withdrawing-room occupied the curved angle of the ward between the hall and the gate-house; beneath it was a ground-floor. The south end of the hall, like the west side, was an outer curtain. It abutted against a half-round tower, 30 feet diameter, with walls 9 feet thick, and a gorge wall, 5 feet thick, flush with the inner face of the curtain. This tower seems to have had an under ground-floor, now filled up. The basement has a door from the court, in the gorge; another door on the west side, probably a postern, and two loops with wide recesses, opening towards the field. The upper floor also had two loops to the field, a window in the gorge, and on each side a door, one leading obliquely into the hall, and the other into a mural chamber within the curtain, and containing a garderobe, double. The floors were of timber. There is no staircase nor fireplace.

The curtain breaks off towards the south-east angle, where it seems to have expanded and probably abutted against a tower. In it is a mural chamber, a garderobe, single, on the first floor level, and which evidently opened from the destroyed tower. The two garderobes mentioned open by oblique shoots in the wall, about 5 feet from the ground, without any projection. As the whole east or ravine front is gone, it is difficult to say whether there were towers at the south-east and north-east angles; probably there were, and round ones. In the north front are two circular depressions, evidently the place of the two towers of the gate-house, and between them is the entrance. This leads from the outer ward, and crossed the ditch upon a causeway of earth, about 6 feet broad at the top, and the ascent up which from the counterscarp of the ditch to the portal is very steep. The causeway appears to be original, and has been pitched with stones on edge. At the end of this ditch, where it opened on the river bank, it is crossed by a curtain, 6 feet thick, intended to prevent enemies from crawling up the river bank and surprising the adjacent gateway. This curtain is now about 6 feet high, and probably was 25 feet or 30 feet.

The outwork, south of the inner ward, and divided from it by a very narrow but deep ditch, is not easily to be explained. It is the extremity of the ridge, of a triangular figure, 60 feet on a side, and level, showing no trace of earthwork or masonry of any kind. The three scarps are very steep indeed, and quite sharp and clean cut, the soft rock being covered with excellent firm turf. This outwork is so dangerously near to the inner ward, and at so high a level, that it must have been occupied, probably by a stockade or timber structure. It is a very curious work.

The outer ward, at the north end or root of the ridge, is 60 feet or 70 feet lower, and much broader than the inner ward. Its defence on the south is the cross ditch, over which passes the causeway to the inner ward; on the west is the river-cliff, 80 feet to 90 feet high; and on the east and north a steep scarp, partly of red rock, partly rivetted in masonry, and from 10 feet to 20 feet deep. Beyond it is the upper part of the ravine, and the natural depression connecting the ravine with the river bank. This ward is something between a square and a circle, and about 300 feet in diameter. It has evidently been defended by a curtain, probably a low one, on the east and south, or exposed, sides, and the ground, usually level, rises in a sort of ramp to what appears to be the remains of the wall. This ramp is wanting on the river and south faces, which, being covered by the river and the river ward, were probably palisaded only. About the centre of the east front is a low mound, apparently the foundations of a round mural tower.

The depressed ground in the centre of the south front indicates that the outer entrance was there; and midway between this and the causeway, leading to the inner ward, are two long heaps of earth and stone with a passage between them. They much resemble the remains of a long gate-house, between the outer and inner gate; but if so, this must have been in the middle of a wall dividing the outer ward into two, of which no trace remains.

This outer ward, never very strong, was evidently intended for the reception of villagers and cattle during the inroads of the Welsh. The earthworks, though deeper and broader than the Normans usually gave to so small a fortress, have nothing of the character of British or Saxon work, and are probably not older than the Conquest, or the reign preceding it. But of the existing masonry none can be safely called Norman. The walls are of inferior and rudely-coursed rubble; no ashlar remains, save a bold cordon or bead, which runs along the top of the lower or battering part of the wall, and this is not carried all round. The arches of the mural tower are flat-pointed. On the whole, the general appearance of the buildings points to the reign of Henry III., and none of it seems of older date. Certainly no decidedly Norman work is seen.

The ditches were substantially dry, though they may have received and retained more or less land-water.

At the base of the slope of the outwork the ravine has been deepened for a rectangular pond, probably a fish-stew, and an early drawing shows water here collected.

Looking from the inner ward upon the river, there is plainly seen, just above the castle, the line of the old mill leat, now a green ditch, and the small eyot upon which must have stood the castle mill. A ripple on the river, here somewhat expanded, shows a ford; and opposite, on the edge of a broad expanse of low, level mead, is the village of Cabalva, said in Welsh to mean a horse-ford. Thus is seen at one view the cliff and the ford which, under the Saxon sway, gave its appellation to the parish, and from which one of the most celebrated of the great English families derived its name.

Clifford, though the cradle of a great race, could have been valuable only while Herefordshire was an unsafe possession. With the settlement of the country under Edward I., it probably fell into disuse and decay. It is far too small and too inconvenient of access to be held, except for safety; and such history as it has is confined to a very early and warlike period.
