What is recorded here
Clonagh Castle rose in 1578 when John Lye destroyed an older religious house and stone cross to build his tower. He turned sacred ground into private strength, proving that local power often feeds on erased memory. The castle later vanished, its stones scattered into Kilshanchoe Church and village walls, while the field remained empty. What was broken twice still lives inside other buildings, waiting to be recognised.
According to O'Leary (1896-99, 135-38) a date stone (KD003-017001-) attests that a castle was built by John Lye in 1578. O'Leary also notes the presence of a 'religious house' (KD003-020----), 'burial place' (KD003-020001-) and stone cross (KD003-02002--) in this area and quotes from a 1608 Inquisition held at Naas that, '… John Lye of Rathbride, gent., being seized of divers lands in the said townland of Clonaugh, levelled the tenements, bounds, and limits of said religious house, threw down and destroyed the cross and trees and erected a tower, or small castle, with other buildings.' Also, according to O'Leary (1904, 172-3) stones from the demolished Clonagh Castle were used to build 'Kilshanchoe Church' (KD003-027----).
On a very slight rise c. 50m to the W of a small N-flowing stream in open pastureland. In 1985 there were no visible surface traces of the monument (SMR file). Two armorial plaques (KD004-002----) incorporated into the walls of a primary school in Johnstown village and an architectural fragment (KD004-003----) incorporated into a modern wall in the village are said to have come from the castle.
