*KILMEHAL (_Cal._, i., 44).--Mr Orpen regards the identification of this castle with Kilmallock as extremely doubtful. *KILMORE (_Cal._, i., 95).--Restored to Walter de Lacy in 1215. Identified with Kilmore, near Lough Oughter, Cavan.[1083] Mr Westropp mentions the motte at this place, which is outside the Anglo-Norman area. The castle was wrecked in 1225 or 1226, and no more is heard of it. The Anglo-Norman advance in this direction failed. *KILSANTAN, Londonderry (_Cal._, i., 70).--Built by John de Courcy in 1197.[1084] Now called Kilsandal, or Mount Sandal, a large motte on the Bann, not far from Coleraine. The castle of Coleraine, inside the town, was built in 1214, apparently of stone,[1085] and probably superseded the castle of Kilsandal. KILTINAN, Tipperary (_Cal._, i., 94).--Castle of Philip of Worcester in 1215. No motte; a headland castle overhanging a river valley. The castle has not only undergone a late Edwardian transformation, but has been cut up to make a modern mansion and farm buildings. No fosses or earthworks remain. [E. S. A.] KNOCK, or CASTLEKNOCK, Dublin (_Cal._, i., 81).--Castle of Hugh Tyrrel. An oval motte, walled round the top, carrying on its edge a smaller motte (with traces of a ditch) on which stand the ruins of an octagonal keep. No other bailey; ditch and bank double for more than half the circumference. [B. T. S.] Fig. 45. *KNOCKGRAFFAN, Tipperary (_Cal._, i., 27).--Castle of William de Braose in 1202. One of the finest mottes to be seen anywhere. Built in 1192, at the same time as the castle of Kilfeakle.[1086] The motte is 55 feet high, has a wide ditch and high counterscarp bank, which is also carried round the ditch of the "hatchet-shaped" bailey, in proper Norman fashion. "There are indications of a rectangular stone building on the flat summit of the mote, and there are extensive stone foundations in the bailey."[1087] *LAGELACHON (_Cal._, i., 95).--Probably Loughan or Castlekieran, in which parish is the great motte of Derver.[1088] LEA, Queen's Co. (_Cal._, i., 30).--Castle of William, Earl Marshall, in 1203. A motte with two baileys; motte entirely occupied, and partly mutilated by a 13th-century keep, with two large roundels. [B. T. S.] LEIGHLIN, Carlow.--Mr Orpen has shown that the fine motte of Ballyknockan answers to the description given by Giraldus of the site of the castle of Lechlin built by Hugh de Lacy.[1089] There is a trace of a possible bailey. The stone castle called Black Castle at Leighlin Bridge is of very late date. Those who believe that we have authentic history of Ireland in the 3rd century B.C. will be able to believe with Dr Joyce that the description of the annalists identifies this motte with the site of the ancient palace of Dinn Righ, burnt by the chieftain Maen at that date!
