What remains today is primarily the western wall of this medieval tower house, rising three storeys high from a motte-like earthwork. The structure, measuring approximately 7.5 by 8 metres, shows signs of considerable alteration over the centuries, including a door that was inserted into the western gable during later renovations. Built from roughly coursed limestone boulders with a slight base batter, the castle once featured a vaulted ground floor according to historical accounts from 1918, though this feature is no longer visible.

The castle's defensive features hint at its turbulent past; remnants of what appears to be a surrounding bawn wall can still be traced at the eastern angle, with a possible curtain tower in the same area. A fireplace and chimney stack mark the southwest angle, practical additions that would have made the tower more habitable during its active use. The site gained historical notoriety during the Irish Confederate Wars when it was attacked in 1641 whilst occupied by Lettice, Lady Offaly, adding a dramatic chapter to its long history.

Archaeological investigations conducted in 2004 as part of planning requirements for nearby housing development revealed little in the way of new discoveries, with test trenches turning up no significant features or finds. To the southwest of the castle lies a 19th-century church, built on the site of an earlier medieval church, creating a layered historical landscape that spans from the medieval period through to modern times. Together, these structures form an intriguing glimpse into the evolution of this corner of County Offaly, from medieval stronghold to Victorian estate.
