What was once likely a late medieval tower house has now been reduced to subsurface foundations, though as recently as 1942, archaeologist Davies documented that the walls' bases were still visible above ground. The southern wall stood three feet high at that time, whilst the northern wall had already deteriorated into an earthen bank, and traces of the western wall could only be revealed through excavation.

The castle's original footprint measured approximately 20 yards from north to south and 25 yards from east to west, with walls constructed from rubble and mortar measuring just over two feet thick. The eastern wall appears to have been completely absorbed into the adjacent lane, where some foundation work may still exist beneath the roadway. Historical accounts from O'Flanagan in 1933 mention the presence of a corner tower and portions of a bawn wall, the defensive enclosure that would have protected the castle grounds; this bawn is now recorded as a separate archaeological feature in the area.

Today, no visible traces remain above ground at the site, making it one of Ireland's many "lost" castles that exist only in historical records and beneath the soil. The Archaeological Inventory of County Offaly, published in 1997, confirms that whilst the castle's physical presence has vanished from view, its historical significance remains documented through surveys and local memory, preserving the story of this once formidable O'Dempsey stronghold in the Irish midlands.
