The first or principal floor contains a state-room, 40 feet by 17 feet, with two large windows opening upon the court, and a fireplace between them. The windows appear to have been of two lights, trefoiled, and they are placed in large, flat, segmental recesses. The roof has been of timber, flat, and rather low. On the same floor are three smaller rooms and a portcullis chamber; and on the east side, over the tank-room, is a vaulted kitchen, with a large fireplace and oven. From the kitchen a small door leads to the east rampart, and along it to the south-east drum tower. Two well-staircases lead to the second floor, which contains also a large chamber, with windows of two lights, and trefoiled, opening upon the court, and a fireplace. Here also are several bedrooms, with doorways of carved ashlar. This floor seems intended for the accommodation of persons of condition. The well-stair at the north-west angle is continued upwards to the watch tower; and from near this stair a narrow door leads to the rampart of the curved curtain, and so to the mural towers of the outer ward. The watch tower is considerably higher than any other part of the castle, and commands an extensive view over both sea and land. [Illustration: KIDWELLY CASTLE. _H. Smyth delᵗ._ _J. H. Le Keux sc._] The lesser or northern gatehouse is in great part destroyed, and appears to have been hastily built. It is on a small scale, and composed only of two half-round towers, the back or gorge walls of which, and part of the portal, have been destroyed. There appears to have been an upper story entered by a staircase in the adjacent western curtain. The portal arch is gone, but there are traces of a drawbridge which worked between two side walls, looped to rake the ditch. That on the east remains. The portal was 10 feet wide, and the bridge dropped with a span of about 18 feet upon a pier still remaining, and projecting from the counterscarp of the fosse. The bridge walls are later than the towers, and these probably than the curtain. This gateway is placed at the north extremity of the outer ward, only a few yards from the river bank. It appears to be an addition. The curtain of the outer ward is in three parts: one, 330 feet long, and curved, encloses the ward on the west or landward side, and connects the gatehouses with the mural towers. This wall is 6 feet thick, and 20 feet high, and is defended by the main fosse. Besides openings from the gatehouses, there is a direct access to this rampart from the court by a mural staircase built against the wall. The rampart walk is protected by a parapet and a rere wall, both of which, to give breadth to the walk, are thrown out upon corbels or false machicolations. The second part of the curtain is straight, or nearly so, and extends 50 feet in length along the river cliff, from the great gatehouse to the south-east drum tower. Its rampart is accessible from each end. This wall is 30 feet high and 7 feet thick.
