What makes the situation quietly odd is where that mound sits: inside a cashel, a type of early Irish stone ringfort, whose enclosing wall was itself largely demolished when the house, and a second dwelling nearby, were built within it. One ancient structure was effectively quarried to build another, considerably more recent one.

The cashel's fate was recorded by the antiquarian Thomas Johnson Westropp, who described it in 1913 as a ring-wall of poor coarse crag slabs nearly levelled when the houses were built in it. Both dwellings appeared on the Ordnance Survey six-inch maps of 1840 and again in 1916, suggesting they were occupied, or at least standing, across that span of decades, though their exact date of construction remains unknown. Today the house in question survives only as a cairn, its rubble sitting on a D-shaped raised platform roughly twenty metres long and ten metres wide, the edge of which is marked by a shallow dip in the ground. A second house lies about seven and a half metres to the west on the same platform, the two ruins occupying what was once the interior of the cashel together.
