The walls survive to only 0.7 metres in height, but the footprint is legible: roughly 6.6 metres east to west, 2.4 metres north to south, with the structure built directly against the western face of a small hillock. Whoever put it here made a deliberate choice of ground, the kind of marginal, water-edged terrain that recurs throughout the Irish landscape wherever people needed to manage livestock, fish, or simply keep themselves apart from the wider world.

The interior was divided into two distinct sectors, suggesting a building with more than one purpose, perhaps a domestic space alongside a small byre or store. A possible entrance on the north-east side would have faced away from the prevailing weather. The date of construction is unknown; the structure has not been firmly assigned to any period, which places it in the company of many small rural buildings in the west of Ireland whose builders left no documentary trace. What can be said is that its position, on a spit surrounded by wetland, follows a logic that is ancient, practical, and still visible in the landscape around Lough Mask and Lough Carra, the twin lakes that define this corner of south Mayo.
