Measuring roughly five metres east to west and just over two metres north to south, the outline of a possible rectangular building survives to the west of a leacht, a small cairn-like stone monument typically associated with early Christian devotional practice, which itself sits to the south-east of a church on the island. The eastern end of the structure is unclear, dissolved into the ground, and several stones poke above the sod without obvious pattern at first glance.

What gives the remains some architectural interest is the wall construction suggested by four parallel slabs. The arrangement points to a double-revetment technique, where two facing lines of stone enclose a rubble or earthen core between them, producing a wall around 0.9 metres wide. This kind of build is found in early medieval contexts across Ireland, though the notes do not confirm a date for this particular example. Its position within what appears to be an early ecclesiastical enclosure, close to both the church and the leacht, raises the possibility that it formed part of a complex of small buildings or ancillary structures associated with that religious site. The detail was recorded by Dr J. Waddell, and the eastern ambiguity he noted suggests the ground has not yet given up everything it holds.
