Though the castle itself has long since vanished, leaving only its memory recorded on old Ordnance Survey maps from 1837 and 1911, the defensive earthworks that once protected it remain clearly visible. The castle originally stood within the southern section of a substantial rectangular enclosure measuring roughly 80 metres north to south and 47 metres east to west, defined by an earthen bank with an external fosse, or defensive ditch.

Today, visitors to the site, located just 55 metres from Williamstown House, can still trace the outline of this impressive bawn; a fortified enclosure typical of Irish defensive architecture. Low stony rises scattered throughout the western side of the enclosure hint at former buildings, though distinguishing between genuine wall footings and natural rock outcroppings requires a careful eye. The lack of standing walls makes interpretation challenging, but the earthworks themselves tell their own story of a time when such defences were essential for survival in rural Ireland.

What makes this site particularly intriguing for historical enthusiasts is how modern technology continues to reveal its secrets. Digital Globe aerial photographs from 2011 clearly show the bawn’s outline from above, demonstrating how even levelled archaeological sites can retain their footprint in the landscape centuries after their destruction. While the castle may have disappeared from view, its defensive perimeter endures as a testament to the strategic importance of this modest rise overlooking the wetlands of Westmeath.
