Wrapping around the western and northern sides of a fortified house and its bawn, an L-shaped walled garden stretches across a gentle ENE-facing slope, its footprint large enough to be conspicuous even now. A bawn, in Irish architectural terms, is the defensive enclosure wall surrounding a tower house or fortified dwelling, and here the garden walls extend well beyond that protected inner space, covering a substantial area that straddles a north-south public road. The larger portion lies to the west, running roughly 160 metres on its longer axis, while a smaller section crosses to the east at the northern end.

The walls themselves are built in clay-bonded rubble, a construction method that relies on compacted earth rather than lime mortar to bind the stonework, making them vulnerable to moisture over time and explaining, perhaps, why the upper portions have narrowed considerably. At the base the walls measure about 0.6 metres wide, tapering to 0.4 metres at the top, and they still stand to a height of around 2.3 metres in places. Three pointed entrances pierce the circuit, two positioned towards the southern end of the south-west wall and a third in the north-west wall, each roughly 2.3 metres wide and 1.8 metres high. The term "robbed" applied to these openings suggests the dressed stonework that would once have framed them has been removed and reused elsewhere, a common fate for cut stone in areas where good building material was scarce. The fortified house and bawn to which this garden belongs are recorded as separate features, giving a sense of how layered this small corner of Roscommon actually is beneath its quiet surface.
