Somewhere in the open pasture of Gragadder, County Kildare, a seventeenth-century structure passed through three quite different identities on paper, without anyone apparently noticing the contradiction at the time. On Noble and Keenan's 1752 map of County Kildare, the site is marked as a functioning farmhouse. Thirty-one years later, on Taylor's 1783 map of the same county, the identical location is recorded as castle ruins. Whether the building genuinely collapsed in that interval, or whether the two cartographers were simply interpreting the same weathered structure differently, the maps leave no answer.

The first edition of the Ordnance Survey six-inch map, published in 1838, shows a building at what is likely the same spot, though it goes unnamed, which was not unusual for minor rural structures at the time. By then the question of whether it was a farmhouse or a ruin may have seemed beside the point. When the site was formally inspected in 1985, any trace of the earlier structure had been replaced by a modern dwelling house, which is where the documentary trail ends. The seventeenth-century building itself, whatever its final condition, left no visible remains by that point.
