Known as the Castle of the Graces, this fortress once stood prominently about 500 yards south of the medieval church, though today only the smallest fragment survives. The historian Carrigan noted in 1905 that alongside these castle remnants lay the extensive ruins of a grand mansion dating to around 1700, suggesting this site witnessed multiple phases of aristocratic occupation over the centuries.

The castle appears on historic Ordnance Survey maps from 1839 onwards, depicted as a rectangular structure measuring roughly 8 metres by 6 metres and oriented northwest to southeast. A wall extending about 4.5 metres northeast from the building's southeastern corner may have been part of a bawn; a defensive wall that typically enclosed Irish tower houses and their outbuildings. These details, carefully recorded by Victorian cartographers, provide valuable evidence of the castle's original footprint and defensive features.

Today, the site sits in mostly reclaimed grassland, and the castle remains are no longer visible at ground level. What was once a symbol of power and prestige has been gradually reclaimed by the landscape, leaving only archival records and maps to hint at its former presence. The transformation from medieval stronghold to early Georgian mansion, and finally to barely discernible ruins, reflects the broader patterns of settlement, abandonment, and agricultural change that have shaped the Irish countryside over the past three centuries.
