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.
