What distinguishes a ditch barrow from its more familiar cousins is precisely what makes it easy to miss: rather than a prominent mound of earth, it is defined by a fosse, a dug boundary ditch, enclosing an interior that sits at roughly the same level as the surrounding land. Without the telltale rise of a burial mound, the monument reads less as an interruption of the landscape and more as a quiet crease within it.

The barrow measures about 5.8 metres across, with a fosse roughly 1.3 metres wide and only 12 centimetres deep, dimensions modest enough to have blended into the undulating pasture for generations before the field survey brought it to light. Wild irises have colonised the northern half of the interior and spill out into the fosse itself, their roots tracing the line of the old ditch in a way that is almost botanical archaeology. The monument does not stand alone; a ring-barrow lies approximately 31 metres to the west, suggesting that this corner of Lissobihane was once a place set apart for the dead, a small funerary landscape now surrounded by pasture and, to the north and east, a former bog that was planted with conifers around the year 2000, steadily reshaping the view the monument has held for millennia.
