The central and larger island is girt by a revetment wall, having half-round bastions, and rising about 15 feet out of the water. This was the wall of the outer ward. About 40 feet within, and concentric with this, are indications of the wall of the inner ward, which was about 8 feet thick and 20 feet high. At each end, connecting the two walls, and occupying the space between them, were the gatehouses, of which that to the south remains, and is a very curious structure. It represents, probably, a late Norman work; but its oldest recognisable part is a doorway of the time of Henry III., surrounded, however, by masonry apparently of that of Edward, his son. A bretache is mentioned in a Survey of 1314, but the present corbels overhanging the gateway, and upon which the timber work rested, appear to be of the age of Richard II., and probably date from 1386. The Constable’s room, placed in the rear, and at the level of the portcullis chamber, is entered through a doorway, the valve of which is original and peculiar, being composed of planks of a taper section, the narrow edge of one fitting into a groove in the back or broad edge of the next. The domestic buildings occupied the north end of the two wards, and are replaced by a modern house, excepting only a vaulted cellar, which may be late Norman, and is certainly the oldest known masonry in the place, and a bracket which supported the ancient oven, and is placed near what (17 Henry VI.) is described as “Una coquina juxta pedem pontis de la Gloriet,” which kitchen was not long since removed. In this ward also, or rather partly in this and partly in the outer ward, near a building of the age of Henry VIII., is a very remarkable bath,—“balnea domini regis apud Ledes,” as it is designated, which was constructed for the use of Edward I. in 1291–2. This is now used as a boathouse. It communicates with the lake by a passage in which are still seen the grooves for the portcullis, and the recesses for the oblique gates by means of which the water was retained or excluded. Mr. Wykeham Martin’s investigations of the accounts relating to this bath are very curious. The hundred Reigate stones, 2 feet square, which are there specified, just tally with the area of the chamber.
