Modern farm buildings and a silage pit now occupy the spot where the castle once stood. Historical maps provide the only clues to its former appearance: the 1838 Ordnance Survey six-inch map shows it as a small rectangular castle positioned within the western section of what appears to be a circular enclosure or earthen bawn, surrounded by a grove of trees.

By the time of the revised 1908 Ordnance Survey 25-inch map, more detail had emerged about the castle's defensive features. The enclosure was depicted as roughly square-shaped, defined by two earthen banks with a wide fosse, or defensive ditch, running between them. However, these fortifications were only visible on the eastern and southern sides of the castle site; the western and northern sides showed no evidence of enclosing elements. A linear bank extended northwest from the eastern side of the enclosure, effectively dividing the interior space of the bawn.

These earthworks would have formed part of a typical Irish castle complex, with the bawn serving as a fortified courtyard that could protect livestock and provide additional defensive capabilities. The O'Carrolls, who held significant power in this region during the medieval period, would have used such fortifications to maintain their territorial control. Though the physical castle has vanished beneath modern agricultural development, the historical maps preserve a record of this once-important stronghold in the Offaly landscape.
