Moated site, Roosky, Co. Mayo
Though the structure has been largely levelled over time, careful observation reveals the ghostly outline of a raised square or circular area, roughly 21 metres across in both directions. The site sits on fairly level ground with pleasant, if not spectacular, views to the south, whilst trees now block much of the eastern vista.
Historical maps tell an intriguing story of this enigmatic earthwork. The 1838 Ordnance Survey depicts it as a diamond-shaped enclosure with straight sides and embankments, suggesting it was far more prominent in the 19th century. By 1919, however, the same survey shows it had already deteriorated into an irregular oblong shape, open on its eastern side. Today, visitors can still trace the low, broad undulations that mark where the original scarps once stood; these are most clearly defined on the southern side, where they reach about 70 centimetres in height and span roughly 5 metres in width.
The presence of a rath, or ringfort, just 80 metres to the southeast hints at a landscape rich in medieval occupation. Moated sites like this one were typically built by Anglo-Norman settlers or wealthy Gaelic families between the 13th and 15th centuries, serving as defended homesteads surrounded by water-filled ditches. Though time and agriculture have softened its edges, this subtle earthwork remains a tangible link to Mayo’s medieval past, compiled for posterity by researcher Jane O’Shaughnessy in June 2020.
