Situated on a NW-facing slope of a prominent hill in the parish of Laracor. The Leyns or Lynch family have been associated with Co. Kildare, but in 1421 Walter Leyns of the Knock is first recorded, and the Lynches continue to be associated with the Knock up to the end of the seventeenth century (Devitt 1909-11, 270). Peter Lynch was implicated in the rebellion of Silken Thomas in 1535 and was attaindered for a period but the family later recovered the Knock (ibid. 274). The ‘new castle on the Knock’ with a great barn adjoining is mentioned in 1609 (ibid. 278). According to the Civil Survey (1654-6) Gerrett Linch of the Knock owned 590 acres there in 1640, and on the premises were ‘two castles, one Mill and divers cabins, and also an old chappell and a stone quarry’ (Simington 1940, 173). He also owned land at Readstowne (102 acres) and had a share in 360 acres at Laracor in the same parish (ibid. 173-6). The castle was besieged and captured by the Royalist, Ormonde, in 1642, and was occupied by Cromwellian forces in 1647 (Devitt 1909-11, 280). The land was forfeited during the Cromwellian period and granted to Henry Jones, the Anglican Bishop of Meath from 1661, who lived in the castle (ibid. 283). Although Garrett had been a Royalist, and three of his sons had died for the cause, he failed to recover the Knock after the Restoration in 1660, and his old property continued in the possession of Jones (ibid. 288). There is an almost complete tower house with good quoins and a base-batter with portion of a later house (ME043-021001-) attached to the SW. The tower house is a rectangular structure (ext. dims 10.1m E-W; 8m N-S) entered through a pointed doorway towards the S end of the W wall. This leads through a lobby to the ground floor apartment, which has an embrasure with a pointed and chamfered light in the N and S walls, and two cupboards in the E wall. A pointed doorway at the N end of the W wall leads to a newel stairs at the NE angle, which has a gun-loop in the W wall and is also accessed by a passage and doorway from the lobby. From the entrance lobby a doorway was broken through the S wall to the later house. From the newel stairs a pointed doorway, now blocked, leads to the first floor under the N-S barrel-vault, the floor of which is supported on corbels in the E and W walls. The only features are a destroyed window in the E wall, a light and a fireplace in the S wall and a doorway in the W wall leading to a passage in the W wall. This passage, which is also accessed from the stairs by a pointed doorway, has a light in its W wall and its S wall was broken through to the first floor of the later house. There is a second gun-loop on the stairs up to the second floor over the vault, which is entered by a pointed doorway. Inside the doorway a destroyed doorway in the N wall leads to a garderobe, which has a cusped ogee-headed light and a slop-stone. The chute from the garderobe debouches on the N wall at ground level. There are rectangular lights at the centre of the E wall of the main chamber and at the NE and SE angles, while the light on the S wall, just W of a fireplace, is pointed. A pointed doorway in the W wall leads to a vaulted passage with one window in the W wall and what is probably a blocked doorway in its S wall leading to the later house. However, this passage does not communicate with the stairs at the NW angle and it had a wooden floor with the joists set into the E and W walls. The third floor is supported on corbels and repeats the lay-out of the second floor and the roof over it was supported on corbels. The stairs continue to the destroyed parapet, where the only features are two chimney stacks rising over the S wall.

In certain instances the entries have been revised and updated in the light of recent research. Compiled by: Michael Moore Date of revision: 13 July 2016
