There remains to be noticed the fragment of a building attached to the southern angle of the keep, and from which evidently sprang the wall which ran between the outer and the inner ward. [B. Fig. _a._] This seems to have been an oblong, divided into two compartments. One, of which much of two sides remains, was 11 feet square, vaulted and ribbed, the fans spreading from the four angles. This was entered on one side from a small Decorated door of 2 feet 3 inches opening, which led into a bent passage. The face towards the inner ward seems to have contained a second small door, by the side either of a window or a larger door. From this chamber a door probably led, through the second chamber, now removed, to the base of the winding steps already mentioned as ascending to the eastern entrance to the keep. The designs of the mouldings of this appended building are peculiarly delicate and graceful, and well executed. This keep is probably the latest example of a rectangular keep as well as a singular one of a keep with its main floor employed as a gatehouse. Its ornaments and details generally are in the late Decorated style, and of the reign probably of Edward II., though it is by no means likely that the work was due to Gaveston. Ashlar masonry is freely employed outside and inside the building, and the details throughout are admirable. It is probable that the addition of the solid buttresses to the curtain was the work of the builder of the keep. The masonry and material correspond. The portcullis grooves are alike, and the solitary stringcourse on one of the bastions is nearly, if not quite, of the pattern of that employed on the keep. It is much to be desired that the inhabitants of Knaresborough would obtain the castle as a promenade, reopen the ditch, or part of it, restore the bridge leading to the outer gate, excavate the foundation of the north-east angle of the keep and of the bridge covering the way into the prison, and check the progress of weather and exposure in the upper portions of the keep. A moderate sum would execute all that is required, and the result would add to the comfort and augment the attractions of the town. LEEDS, OR LEDES, CASTLE, KENT. Leeds Castle is a very peculiar structure. It stands upon three rocky knolls, of which two are islands in a lake of 15 acres, and the third occupies the central part of the artificial bank by which, as at Kenilworth and Caerphilly, and in some degree at Framlingham and Ragland, the waters are or were retained.
