The castle ruins sit atop a motte-like earthwork, with traces of what appears to be a surrounding bawn wall still visible at the eastern angle. Though considerably altered by later occupants of the adjoining house, the structure retains enough of its original character to reveal its defensive past.

Today, only the western wall of the tower house survives, rising three storeys high and constructed from roughly coursed limestone boulders with a slight base batter that would have helped deflect projectiles. A later doorway was inserted into the western gable, likely when the castle was incorporated into the 19th-century residence. The ground floor was originally vaulted according to historical accounts, and you can still spot the fireplace and chimney stack at the southwest angle, along with what may be the remains of a curtain tower at the eastern angle of the bawn.

The castle’s turbulent history includes a notable siege in 1641, when the Irish Confederate army attacked whilst it was occupied by Lettice, Lady Offaly. Just southwest of the castle stands a 19th-century church, built on the site of an earlier medieval church, creating a landscape where different periods of Irish history overlap. Archaeological surveys conducted for the Archaeological Inventory of County Offaly have helped piece together this complex site, though recent research continues to reveal new details about its long occupation and various transformations through the centuries.
