The earlier lords, both Saxon and Norman, who gave name to, and derived their names from, Bodiham, pitched their homestead on the north side of the high ground, some way from the church, and upon the right bank of the Kent Ditch, where the site is still indicated by some earthworks and a moat. Nearer to, but south of the church, on the brow of the hill, above the present castle, are the remains of another earthwork, rectangular and oblong in form, the site probably either of an early residence or a still earlier encampment.

Below this brow, on the southern verge of and just within the slope, it pleased a Lord of Bodiham, having become so by marriage with its heiress, to establish a new residence. Sir Edward Dalingruge, a successful soldier in the rough school of the Black Prince and his captains, of whom his immediate chief, Sir William Knollys, was one of the roughest, having held offices of trust under Richard II., decided here to build a castle suitable to his rank, wealth, and military fame; and having, in the 9th of Richard, 1385–6, obtained the royal licence, he constructed at a vast cost, both in earthwork and masonry, the castle here described.

Bodiham is a building of very high interest. It is a complete and typical castle of the end of the fourteenth century, laid out entirely upon a new site, and constructed after one design, and at one period. It but seldom happens that a great fortress is wholly original, of one, and that a known, date, and so completely free from alterations or additions. It has, moreover, fallen into good hands. Enough, and not too much, has been done to arrest the effects of time and weather. The repairs have been well executed, and in Wadhurst stone, the proper material; and, though well watched, it is open to all who care to visit it.

In plan and details Bodiham belongs to the early Perpendicular style, and occupies a mean position between Caerphilly, a work late in the thirteenth century, and Wressil, only a few years later than Bodiham in time, but much later in style and arrangements. Like these castles, it has no keep, and its domestic buildings are constructed within and against the walls of a court, but while Caerphilly, like Harlech and Ledes, is concentric, and has a narrow outer ward, Bodiham and Wressil, like Bolton, have but one ward, one line of defences, and are only rectangular enclosures, with strong and lofty curtains, flanked by still more lofty mural towers. Pennard in Gower, though of the reign of Henry III. or his son, is, on a small scale, of the same general type as Bodiham.

Save the adjacent river and the marsh, the immediate site of Bodiham possesses no natural advantages. A sort of platform was selected upon the sloping ground, about 30 feet above the river’s level, and in it was excavated a rectangular basin, 180 yards north and south, by 117 yards east and west, and about 7 deep. To the east, the containing bank was wholly artificial, formed of the excavated material, as was also the case with the contiguous parts to the north and south. The remaining part of the south bank was also slightly raised.

On the west side, near the north end, a small natural combe descended towards the excavation, of which, being wet, it was regarded as the future feeder. A strong dam was thrown across the lower part of this combe, between it and the excavation, of which it thus formed the bank. No doubt the pool so penned in was intended as a store pond when the moat was low.

In the centre, or nearly so, of the excavation, was left a rectangular island of rather above half an acre in area, raised artificially about four feet, and to be occupied by the future castle, of which the ground plan would thus be a plot of about 50 yards by 46 yards, surrounded by a wet moat from 35 to 65 yards broad. At present a sluice is provided for the occasional emptying of the moat, and probably something of the sort was originally constructed, though it would, of course, be concealed. The fact is, however, that a few vigorous workmen could at any time have cut through the bank in a few hours, and thus have deprived the castle of one of its defences. The mud, however, until dry, would be even a better protector than the water.

Bodiham Castle, then, is a rectangular enclosure 152 feet north and south, by 138 feet east and west, contained within four curtain walls. At each angle is a drum tower, 29 feet diameter, and of three quarters projection, flanking the several faces. In the centre of the north face is the great, and of the south face the lesser, gatehouse, and in the centre of each of the other faces is a square tower. There are thus eight mural towers, four cylindrical, and four rectangular, giving an agreeable variety to the outline. Besides these there is a projection from the east face of 8 feet, containing part of the chapel and the sacristy. The walls and towers all rise direct from the water. The curtain is 40 feet 6 inches high from the water to the crest of the parapet, and the towers are one-third higher, or 54 feet. The outer walls generally are 6 feet 6 inches thick, which is also the height of the parapets. The stair turrets rise 14 feet higher than their towers, and the chimneys about 9 feet. Both are octagonal, and are crested with miniature battlements in the late Perpendicular manner. There is no water gate or postern, such as those at Ledes and Caerphilly.

The great gatehouse is a very imposing structure. It is in plan a T, the horizontal limb forming the front of 30 feet breadth, and the vertical limb extending backwards as far, and containing the entrance passage. The front is composed of two towers, rectangular, but having the angles largely recessed, so as to throw forward the central part of each tower as a bold buttress, 15 feet broad by 6 feet deep. The whole projects from the curtain about 15 feet, and between the towers, deeply sunk, is the gateway.

The gateway has a slightly four-centred arch, very plain, and set in the usual square-headed shallow recess, intended apparently to receive the platform of the bridge when lifted. There are traces of the chain holes in the spandrels. The whole is placed in a deeper and plain recess, terminating above in a four-centred arch, which carries the parapet, and has behind it three machicolations which protect the entrance. Over the door is the usual portcullis chamber window, and right and left other windows, all small and lancet, some trefoil-headed, and some plain. Two pairs of loops command the approach, one pair has oylet holes at each end of the slit. The other pair have holes, rather larger, at the lower end only. It is the style of loop that marks the introduction of fire-arms. In the jambs of the portal is a half-round portcullis groove, and a little within a pair of folding doors. The entrance passage, 12 feet broad and 30 feet long, is unusually lofty. It is divided by a cross arch into two chambers, both vaulted. The first, 18 feet long, has on the right and left small lancet doors, leading by a narrow vaulted and ribbed mural passage into the lodges, 11 feet by 10 feet. On the left is a second door opening on a circular well-stair, 8 feet diameter, and unusually steep, leading to the upper chambers and roof, and terminating in a turret at the angle of the gatehouse. The vaulting has fallen in, but it is clear that it resembled that of the second chamber. Beneath the cross archway is a second portcullis, and beyond it the second part of the passage. This is 12 feet square, without lateral doorways, and vaulted. The vault is of four cells, three ribs and two half or wall-ribs springing from each corner corbel, and meeting in one central, four lateral, and four half bosses, placed upon two cross or ridge ribs. They are pierced as in the inner ward gate of the Tower of London, and possibly each contained a flower. The openings are, of the central boss 6 inches, and of the others, 4 inches diameter. These apertures can scarcely have been meant for defence; they are too small, and do not command the four corners of the passage. No doubt a long pike might be thrust down some of them, but scarcely, to be of use, down the half holes next the walls. As to pouring down melted lead, pitch, or oil, such articles were always too expensive to form a part of the regular munitions against a siege, nor is there here, nor in portcullis chambers generally, any furnace for heating such materials in any quantity.
