The main approach to the castle lies through the town, on leaving which, a road, passing the church, leads up to the entrance, and crosses the ditch by a permanent bridge, by which the draw-bridge was superseded by Henry Lord Berkeley in 1587, and beyond and partly standing in which is the outer Gate-house. This is a rectangular building of no great merit, pierced by a portal having a low drop arch on each face. The passage is plainly vaulted in calcareous tufa, and in the crown of the vault are three square holes or meurtrières. There is no upper story, nor, at present, are there any flanking towers or curtain. There is a basement below the road-way level, entered from the ditch, but, probably, at one time filled with earth. This gate-house may be of Decorated date. It has no portcullis. From the ditch, the side walls of the bridge look original, and may have been, as at Goderich, the lateral walls between which was the pit of the draw-bridge.
Entering the outer gate, the visitor finds himself upon a triangular platform, of which the outer gate-house is the apex, and the inner gate-house and part of the keep the base; on the left a modern wall, which replaces the curtain, crests the scarp of the ditch, and forms the north side of the platform 66 yards long. On the right a low parapet, 54 yards long, forms the south side, and caps a revetment wall of about 10 feet in height, at the foot of which the ancient scarp has been laid out in good taste in a terrace garden. This triangular platform is scarcely an outer ward: it is rather a barbican covering the main entrance and the keep. Its area is 7,750 square yards. There is no trace of a second ditch in advance of this side of the keep and the inner gate, but it is very probable that there was one, though, if so, it must have been filled up when the courts were added to the keep, as otherwise it would have completely occupied them.
The keep covers about 35 yards, or above half of the base of the barbican, and lies to the left or north of the gate-house. Part of it has been removed and a large breach formed, showing that the interior is full 22 feet above the ground level outside. The inner Gate-house is in the same position as at Alnwick. It is in truth not a regular gate-house, and has no flanking towers or machicoulis, but the entrance passage pierces a lofty pile of buildings which connect the domestic apartments with the keep, and complete the circle of the main court. The portal is about 11 feet broad and 30 feet deep, and its roof is flat and of timber. It has two drop arches. On the right is a lodge door, and the inner archway has a half round portcullis groove. Above are two stories through which are doors, no doubt modern, into the keep. Probably the Norman entrance was here, a mere opening in the wall. Much of the structure seems Decorated with later alterations. South of, and flanking the gate, between it and the south-east angle of the place, is a small Tudor building.
The gateway opens into the Great Court of the castle, a roughly rectangular space, having the circular keep encroaching considerably upon its north-west angle, and the remainder of the space set round with domestic buildings built against and completely concealing the lofty curtain.
This court, which is, in fact, the castle, measures outside upon its south face 60 yards, and its east face 72 yards, these two being set nearly at right angles. The north and west faces are about 60 yards and 76 yards, but the north-west angle is occupied by the keep, which covers about 40 yards of the north, and 42 yards of the west face, forming a part of the enceinte. The buildings project about 30 feet, so that the inner and open part of the court is much reduced in area. The curtain, originally thick, has been strengthened outside, probably in the Decorated period, by nearly thirty broad and thick and very clumsy buttresses, some of which probably conceal the early Norman pilaster, for most of the wall is certainly of that date. Some of these buttresses are pierced by loops, showing an immense thickness of wall.
On entering the court, on the left is the high plain wall of the keep, with its forebuilding and exterior staircase ascending to the entrance. On the right are domestic buildings, drawing-rooms, bed-rooms, &c., extending to the south-east corner. The face wall, though much altered, and pierced with Tudor windows, seems in substance Norman with large Decorated alterations. The pointed Norman arches may be traced in the wall. These buildings have a basement and two upper stories. It is uncertain whether they stand upon a vault.
The chapel occupies the south-east angle. The hall is next to it along the east side, and the butteries, kitchen, and offices fill up the north-east angle and the north side as far as the keep. In the south wall, near the gate-house, but at the exterior ground level, is a small pointed doorway, probably a postern, and connected with it a small chamber, about 6 feet below the level of the court, of doubtful age, but with an old doorway. It has a flat roof, and wooden floor of the room above: being filled with the bins of a modern cellar, it cannot be examined.
The Chapel, dedicated to the Virgin, rests on the vault of the great cellar, and measures 29 feet by 18 feet. It is entered by a modern door in the north wall, west of which are traces of what seems to have been the original entrance. It has a rather flat apsidal east end of three faces; the vestry, a mural chamber, opening in that to the south-east. The south side is the outer wall, 14 feet thick; it is pierced by a mural passage, a sort of aisle, at the floor-level, which opens into the chapel by four foliated arches, each corresponding to a window or loop in the curtain. There is a small Decorated piscina. Against the west wall is a sort of pew of two stages, the upper being an enclosed gallery for the family, opening from the principal rooms.
The roof is open, at a very low pitch, with timber ribs rising from corbels. These, with cross ribs, divide the roof into large panels of a very curious character. The walls of the chapel are Norman, but the roof and fittings are mostly Decorated. Maurice, Lord Berkeley, 38 Edward III., obtained from Pope Urban II. a bull bestowing certain spiritual privileges upon all who worshipped here or in the chapel in the keep.
The Cellar below the chapel is part of the original castle. Its level is a little below the floor of the hall. It is in plan an equilateral triangle about 40 feet in the side. Its roof is vaulted and groined in three hexagonal bays, springing from three shafts of late Norman character. Nine triangular vaultings, abutting on the walls, complete this very curious roof. Opening from this is another vault, also a cellar, at a lower level by about 5 feet. It is much smaller, and has a ribbed and vaulted roof. Unfortunately it is used as a cellar, and obscured by modern fittings. It has a small Tudor window.
