These are the grass-covered wall-footings of a small building, tucked off-centre towards the southern angle of a bawn, the kind of defensible stone enclosure that was typically built around tower houses in late medieval and early modern Ireland to protect livestock, outbuildings, and the approaches to the main structure. The position suggests it was a working part of the complex rather than an afterthought.

The building forms part of a broader cluster of remains associated with Graystown Castle, which lies two fields to the south. That cluster includes a rectangular tower, a bawn to its east, a house with its own separate bawn, and at least two further outbuildings. To the south again lies a deserted medieval settlement, making the wider landscape here a layered record of occupation, abandonment, and gradual return to farmland. The small building inside the bawn is understood to be associated with the castle complex, though its precise function is uncertain. The site sits on a slight rise with open views in all directions, a characteristic that would have mattered considerably to whoever chose to build here.
