When surveyors first recorded it in 2010, it amounted to little more than a grass-covered platform, roughly 12 to 14 metres along its longer axis, with a scatter of large stones along two of its sides that seemed to mark the line of former wall footings. It appeared on neither the 1838 nor the 1922 Ordnance Survey six-inch maps, meaning it had either fallen below the threshold of cartographic interest or had already largely disappeared by then. Shortly after it was recorded, it was levelled during land reclamation work, leaving the site as unmarked pasture.

What makes its disappearance feel like more of a loss is the local memory attached to the surrounding area. A field immediately to the south has long been known as the Castle field, and that tradition may point toward something considerably more significant. A castle and associated settlement in this townland of Ross appear in the Stafford Inquisition of County Mayo, a seventeenth-century legal survey of landholding carried out under Sir Francis Stafford, which records the property as the castle, town and lands of Rosse, commonly called Rosse Mc Paddin. The personal name embedded in that placename, Mc Paddin, suggests a specific family or individual once held this ground, though the record does not elaborate further. Whether the stone platform recorded in 2010 was a remnant of that castle complex, a later outbuilding, or something else entirely, was never established before the ground was cleared.
