Historical maps tell the story of its gradual disappearance; the 1837 Ordnance Survey shows it as a clear rectangular enclosure, whilst by the 1909 edition it had already begun to lose its sharp edges, appearing more sub-rectangular in form. The site measured roughly 50 metres from east to west and 40 metres north to south, making it a fairly typical size for such defensive homesteads.

The enclosure survived in some form until around 1950, when it was finally destroyed, likely during agricultural improvements or land clearance that swept through much of rural Ireland in the mid-20th century. Today, visitors to the site will find only a low mound marking where this once-substantial structure stood. The earth here still holds the memory of the defensive ditch that would have surrounded the central platform, which typically would have held a timber or stone building.

Moated sites like this one at Grangeford were particularly common in the eastern counties of Ireland, often built by Anglo-Norman settlers or prosperous Irish families during the 13th and 14th centuries. They served as fortified farmsteads; not quite castles but certainly more defensible than ordinary homes, with their water-filled ditches providing both protection and a statement of status in the medieval landscape.
