This four-storey limestone tower house, measuring 10 metres by 7.44 metres, was built with the defensive features typical of its era: a sturdy base-batter, dressed quoins, and a pointed doorway that was once protected by a yett (iron grille gate). Just 33 metres northeast of the tower lies a small limestone quarry, whilst stone walls run up to the castle’s corners, enclosing this monument that has been protected under preservation order since 1934.

The castle’s turbulent history begins in 1593 when Thomas Mac Donnogh Ro O’Carran was convicted of high treason, leading to the confiscation of his castle and lands. George Sherlock received the property as a grant but quickly sold it to the Earl of Ormond for £80. By the time of the Civil Survey in the 1650s, the castle was described as “wanting repaire” and had passed into the ownership of Nicholas Everard of Fethard. The tower’s defensive design is evident in its layout; visitors entering through the south doorway would find themselves in a small lobby area defended by a cross-loop, with access to the spiral staircase tucked into the southwest angle and the main ground floor chamber beyond.

Though time has taken its toll, with the battlements now lost and several windows broken out, the castle retains fascinating architectural details. Each floor served distinct purposes, from the ground floor chamber with its three windows and wall cupboards, to the upper levels featuring large fireplaces that were later modified with stone and brick infill. The second floor’s ogee-headed windows and the remarkable third-floor chamber with its vaulted ceiling, still showing original wicker-centring marks, reveal the craftsmanship of medieval builders. Above it all, a loft space roofed with a pointed vault once provided additional storage, whilst the finest room appears to have been on the third floor, boasting windows on all four walls including an elegant two-light, cusped ogee-headed window facing northeast.
